This means that a subject having good visual acuity (1.0 or more) with both eyes can visually recognize the subject when looking at the subject.

  In the present embodiment, the slit is a portion where the absorbing material constituting the absorbing core 50 is not substantially disposed. In the slit, a portion where the basis weight of the absorbing material is 0 or an absorbing material spilled from the periphery is disposed, but the absorbing material in the design is a portion where the absorbing material is 0. The slit absorbs deformation or serves as a base point of deformation when the absorbing core 50 receives a force. The slit may have a pair of auxiliary slits 54, a pair of side slits 52, and a central slit 55. The side slits 52 constitute the crotch marks of the present invention.

  As shown in FIG. 3, the absorbent core 50 includes a first region R1 sandwiched between a pair of side slits 52, a second region R2 located between the side slit 52 and the outer edge 50S of the absorbent core 50, And a fourth region R4 located between the auxiliary slit 54 and the outer edge of the absorbing core 50. In FIG. 3, the first region R1, the second region R2, the third region R3, and the fourth region R4 are shown with different hatching. The second region R2 is located outside the width direction W of each side slit 52 and is provided as a pair. The first region R1 and the second region R2 are regions that extend from the side slits 52 along the width direction W. The third region R3 is located outside the auxiliary slits 54 in the width direction W, and is provided as a pair. I have. The third region R3 and the fourth region R4 are regions extending from the auxiliary slit 54 along the width direction W.

  The auxiliary slit 54 may be configured to deform the absorbing core 50 in the thickness direction T. The absorbing core 50 is configured to be deformed with the auxiliary slit 54 as a base point when receiving a force at the time of wearing or the like. The auxiliary slit 54 is located on the front side of the side slit 52 and may be arranged at least in the front side area S1. The front edge 54F of the auxiliary slit 54 may be disposed in the front side area S1, and the rear edge 54R of the auxiliary slit 54 may be disposed in the crotch area S3. At least a portion of the auxiliary slit 54 extends outward in the width direction W toward the front side in the front side area S1.

  Although the front mark portion of the present embodiment is constituted by the auxiliary slit 54, the front mark portion is not limited to this. The front mark portion may have any configuration as long as it is visible from the skin side T1 and the non-skin side T2 of the absorbent article 10, and the absorbent material of the absorbent core 50 has a low basis weight area where the basis weight of the absorbent material is lower than the surrounding area. The core 50 may be configured by at least one of a pressed part obtained by compressing the core 50 in the thickness direction T, a slit formed in the absorbent core 50, and a difference in rigidity of the absorbent core 50.

Extends to the side.

  The auxiliary slit 54 forming the front mark portion extends outward in the width direction W toward the front side, and is arranged along the groin portion of the wearer. The shining portion is hard to hide by clothes or an absorbent article being worn, and is easy to see by a wearing assistant positioned on the side of the wearer. Therefore, at the time of wearing, the auxiliary slit 54 can be aligned with the groin of the wearer, and the absorbent article 10 can be adjusted to an appropriate position. After the wearing, the auxiliary slit 54 can be visually checked from the non-skin side T2 of the absorbent article 10 to check whether the auxiliary slit 54 is located at a position corresponding to the indentation. Therefore, the wearing assistant can grasp from the non-skin side of the absorbent article whether or not the absorbent article has been attached to the correct position.

  Further, since the front mark portion is the auxiliary slit 54, the absorbent core 50 is easily deformed with the auxiliary slit 54 as a base point when worn. Thus, the auxiliary slit 54 can be positioned along the indentation while the auxiliary slit 54 is aligned with the indentation. Therefore, the absorbent article can be positioned at an appropriate position, and the absorbent core 50 can be arranged along the groin. Also, as shown in FIG. 6, when the absorbent core 50 is deformed from the auxiliary slit 54 as a base point, wrinkles are generated around the auxiliary slit 54 on the skin surface and the non-skin surface of the absorbent article 10. The wrinkles serve as a mark, and the auxiliary slit 54 can be more easily arranged with respect to the indentation.

  The front side area S1 of the absorbent article 10 is deformed with the auxiliary slit 54 as a base point. The auxiliary slit 54 extends outward in the width direction toward the front side, and is deformed along the recess. The third region R3 between the auxiliary slits 54 covers the swelling of the body between the indentations, and the fourth region R4 outside the auxiliary slit 54 in the width direction W is closer to the skin surface T1 than the third region R3. Bend. In the cross section along the width direction W, the front side area S1 is deformed into a curved shape that covers the body.

  As shown in FIG. 5, the skin sheet 41 and the non-skin sheet 42 may be joined in a region overlapping with the auxiliary slit 54. In the present embodiment, the core wrap 56 as the skin sheet 41 and the core wrap 56 as the non-skin sheet 42 are joined in a region overlapping the auxiliary slit 54. Since the skin sheet 41 and the non-skin sheet 42 are joined, the auxiliary slit 54 is in close contact with the skin sheet 41 and the non-skin sheet 42, and the visibility of the auxiliary slit 54 is improved. By improving the visibility of the front mark portion, it becomes easier to adjust the absorbent article to an appropriate position.

  Further, in order to enhance the visibility of the auxiliary slit 54, a press working in the thickness direction T may be performed on the inner edge and the outer edge of the auxiliary slit 54. By performing the press working on the inner edge and the outer edge of the auxiliary slit 54, the visibility of the edge of the auxiliary slit 54 is improved, and the visibility of the front mark portion can be improved.

  The absorbent core 50 may have a crotch mark. The crotch mark is a mark for positioning the crotch of the wearer when worn, and is visible from the skin side T1 and the non-skin side T2 of the absorbent article. The crotch mark part of the present embodiment is formed by the side slit 52 formed in the absorbent core 50. The side slit 52 as a crotch mark portion is configured to be visible from the skin side T1 of the absorbent article 10 via the skin sheet 41, and the non-skin of the absorbent article 10 is It is configured to be visible from the surface side T2.

  Although the crotch mark of the present embodiment is constituted by the side slits 52, the crotch mark is not limited to this. The crotch mark portion may have any structure as long as it is visible from the skin side T1 and the non-skin side T2 of the absorbent article 10, and the absorbent core 50 has a low basis weight area where the basis weight of the absorbent material is lower than the surrounding area. The core 50 may be configured by at least one of a pressed part obtained by compressing the core 50 in the thickness direction T, a slit formed in the absorbent core 50, and a difference in rigidity of the absorbent core 50.

  The side slit 52 may be arranged at least in the crotch region S3. The front edge 52F of the side slit 52 may be disposed in the crotch region S3, and the rear edge 52R of the side slit 52 may be disposed in the crotch region S3. The side slit 52 only needs to extend at least in the front-rear direction L, and may extend along the front-rear direction L or may have a portion inclined with respect to the front-rear direction L. The length of the side slit 52 in the width direction W may be constant or may vary. The side slits 52 may not be provided at the center of the absorbing core 50 in the width direction W, but may be provided as a pair symmetrically with respect to the center of the absorbing core 50 in the width direction W.

  By providing the side slits 52 in the absorbent core 50, positioning with respect to the body can be performed by the side slits 52 on the crotch side of the groin portion. The side slits 52 extend in the front-rear direction L, so that the crotch region S3 can be easily arranged along the front-rear direction L of the body when worn. Further, after the wearing, it is possible to grasp whether or not the crotch region S3 is correctly arranged from the non-skin side T2 of the absorbent article 10. The auxiliary slit 54 extends outward in the width direction W, and the side slit 52 extends in the front-rear direction L. Since the directions in which the auxiliary slits 54 and the side slits 52 extend are different, the boundaries are easily noticeable. Therefore, it is easy to grasp the area to be arranged along the indentation, and it is easy to adjust the absorbent article 10 to an appropriate position.

  In addition, since the crotch mark is the side slit 52, the absorbent core 50 is easily deformed with the side slit 52 as a base point when worn. Specifically, in a state where the absorbent article 10 is worn, the absorbent article 10 is sandwiched between the legs, so that a force is applied to the crotch region S3 toward the inside in the width direction W by the legs. When a force inward in the width direction W is applied to the absorber in the crotch region S3, the side slits 52 of the absorption core 50 are deformed, and the second region R2 moves inward in the width direction W, and the width direction of the absorption core 50 is changed. The length of W becomes shorter. The absorbent core 50 can enter inside in the width direction by the side slits 52 in the crotch region S3. Since the length in the width direction of the absorbent core 50 in the crotch region S3 is short, the absorbent core 50 can easily fit in the crotch, and the discomfort during wearing can be suppressed. Therefore, while positioning with respect to a crotch by the side slit 52, the crotch area | region S3 can be arrange | positioned in the area | region between both legs. Therefore, the absorbent article can be adjusted to an appropriate position, and the absorbent core can be arranged in a more suitable compact state.

  As shown in FIG. 4, the skin sheet 41 and the non-skin sheet 42 may be joined in a region overlapping with the side slit 52. In this embodiment, the core wrap 56 as the skin sheet 41 and the core wrap 56 as the non-skin sheet 42 are joined in a region overlapping the side slit 52. Since the skin sheet 41 and the non-skin sheet 42 are joined, the side slits 52 adhere to the skin sheet 41 and the non-skin sheet 42, and the visibility of the side slits 52 is improved. By improving the visibility of the side slits 52, it becomes easier to adjust the absorbent article to an appropriate position.

  Further, in order to enhance the visibility of the side slits 52, a press working in the thickness direction T at the inner edge and the outer edge of the side slits 52 may be performed. By performing the press working on the inner edge and the outer edge of the side slit 52, the visibility of the edge of the side slit 52 is enhanced, and the visibility of the crotch mark portion can be enhanced.

  The width of the auxiliary slit 54 may be shorter than the width of the side slit 52. The width of the side slit 52 is a length in a direction orthogonal to the longitudinal direction of the side slit 52, and in the side slit 52 extending in the front-rear direction L, the length in the width direction. Similarly, the width of the auxiliary slit 54 is a length in a direction orthogonal to the longitudinal direction of the auxiliary slit 54, and is the width in the auxiliary slit 54 extending in the front-rear direction L. When the side slit 52 and the auxiliary slit 54 are integrated, the boundary between the side slit 52 and the auxiliary slit 54 may be a portion where the width changes. In the configuration in which the width of the side slit 52 and the width of the auxiliary slit 54 are changed, the maximum width of the auxiliary slit 54 may be shorter than the maximum width of the side slit 52, or the average width of the auxiliary slit 54 may be smaller. It may be shorter than the average width of the side slits 52.

  The auxiliary slit 54 is a mark for positioning with respect to the groin portion in the front side area S1, and is more easily visually recognized than the side slit 52 provided in the crotch area S3. Therefore, even if the width of the auxiliary slit 54 is shorter than the width of the side slit 52, the function of the front mark portion is easily exerted. In addition, since the width of the auxiliary slit 54 is different from the width of the side slit 52, the wearer can easily distinguish and grasp the auxiliary slit 54 and the side slit 52. By grasping the boundary between the auxiliary slit 54 and the side slit 52, it is easy to grasp the area to be arranged along the indentation, and it is easy to align the absorbent article 10 at an appropriate position.

  If the length in the width direction of the auxiliary slit 54 is too long, the length in the width direction of the portion where the absorbent core 50 is deformed is long, and the length of the portion where the absorbent core 50 is arranged along the body is short. , There is a possibility that a leak may occur in the front side area S1. However, since the width of the auxiliary slit 54 is shorter than the width of the side slit 52, the length in the width direction of the absorbing core 50 in the front side area S1 is secured, and leakage in the front side area S1 can be suppressed. As shown in FIG. 6, the absorbent core 50 can be fitted along the groin of the wearer while suppressing leakage in the front side area S1.

  The width of the auxiliary slit 54 is set to be a side slit in order to suppress an uncomfortable feeling when worn in the crotch region S3 and to obtain an effect of fitting along the groin of the wearer while suppressing leakage in the front side region S1. The width may be equal to or less than に 対 す る of the width of 52. It is possible to suppress the distance in the front side area S1 to move inward in the width direction while securing the distance to move inward in the width direction by the side slits 52.

  The central slit 55 may be located between the side slits 52 in the width direction W and extend in the front-rear direction L. The center slit 55 may be separated from the side slit 52 in the width direction, and may be separated from the auxiliary slit 54 in the width direction. At least a part of the center slit 55 may be arranged in the crotch region S3. The front edge 55F of the central slit 55 may be disposed in the crotch region S3, and the rear edge 55R of the central slit 55 may be disposed in the rear region S2. The center slit 55 may be deviated rearward from the side slit 52, and the front edge of the center slit 55 may be located rearward of the front edge 52F of the side slit 52. The central slit 55 only needs to extend at least in the front-rear direction L, and may extend along the front-rear direction L, or may have a portion inclined with respect to the front-rear direction L.

  The first region R1 is easily bent in the thickness direction T by the central slit 55, and the overall length of the absorber in the width direction can be further reduced. More specifically, when a force is applied from the outside to the inside in the width direction at the time of wearing, the inside edge of the first region R1 is located on the skin side starting from the outside edge (side slit 52) of the first region R1. The absorbent core 50 is easily deformed so as to move. Therefore, the length in the width direction of the absorbent core 50 is likely to be shorter. The absorbent core 50 in the crotch region S3 is deformed to have a convex shape with the center in the width direction of the absorbent core 50 as an apex, and the overall length of the absorbent core 50 in the width direction can be further reduced.

  Further, when the absorbent article 10 is used, the absorbent pad may be used by overlapping the absorbent pad on the skin side of the absorbent article 10. At this time, in the crotch region S3, the second region R2 of the absorbent core 50 moves to the skin surface side T1 of the first region R1, so that the skin surface of the absorbent core 50 is pushed up to the wearer side, and the absorbent pad is removed. Can be placed closer to the skin surface. The absorbent pad is fitted to the body and leakage can be further suppressed. In the front side region S1, the fourth region R4 is deformed so as to rise to the skin surface side with respect to the third region R3 with the auxiliary slit 54 as a base point. By arranging the absorbent pad in the third region, the outer edge of the absorbent pad can be held so as to be sandwiched by the fourth region. As described above, since the absorbent core 50 is deformed along the recessed portion while holding the absorbent pad, the absorbent pad can be arranged along the region between the recessed portions.

  The maximum length of the third region R3 in the width direction W may be longer than the maximum length of the first region R1 in the width direction. The third region R3 sandwiched by the auxiliary slits 54 can secure the length in the width direction W more than the first region R1 sandwiched by the side slits 52, and can cover the body with the absorbent core 50 in a wide range. The length in the width direction of the absorption core 50 in the front side area S1 can be secured, and leakage in the front side area S1 can be suppressed.

  The side slit 52 is located inside the outer edge 50S of the absorbent core 50 in the width direction, and does not need to reach the outer edge 50S of the absorbent core 50. According to this configuration, the absorbing material exists outside the side slits 52 in the width direction W. The body fluid diffused by the side slits 52 is retained by the absorbing material, and lateral leakage can be suppressed.

  The rear edge 52R of the side slit 52 is located in the crotch region S3, and the side slit 52 does not have to reach the rear region S2. According to this configuration, the region where the length of the absorber in the width direction W is short is less likely to reach the rear region S2, and the absorbent core 50 of the rear region S2 can be applied to the body with a wide width to prevent leakage.

  The auxiliary slit 54 is located inside the outer edge 50S of the absorbent core 50 in the width direction and does not have to reach the outer edge 50S of the absorbent core 50. According to this configuration, the outer edge of the absorbent core 50 can be applied to the body in a planar manner without being deformed by the auxiliary slit 54. Therefore, leakage in the front side area S1 can be further suppressed. When the auxiliary slit 54 is formed of a slit, the absorbing material exists outside the auxiliary slit 54 in the width direction. The body fluid diffused by the auxiliary slit 54 is retained by the absorbing material, and lateral leakage can be suppressed.

  A leg elastic member 67 that contracts in the front-rear direction L may be provided outside the second region R2 in the width direction. The second region R2 is pulled up to the skin surface side T1 by contraction of the leg elastic member 67, and when a force is applied from the outside to the inside in the width direction at the time of wearing, the second region R2 becomes the skin surface side of the first region R1. It becomes easy to move to T1 and the inside of the width direction. Therefore, the length of the absorbent core 50 in the width direction is easily reduced.

  The absorbent core 50 may have a constricted portion 51 whose length in the width direction W is shorter than the maximum width of the absorbent core 50. The region having the maximum width 50M of the absorbent core 50 is arranged so as to straddle the front side region S1 and the crotch region S3, and is arranged so as to straddle the rear side region S2 and the crotch region S3. The constriction 51 of the absorbent core 50 may be arranged in the crotch region S3. Since the length in the width direction W of the absorbent core 50 in the crotch region S3 sandwiched by the wearer's crotch is short, the absorbent core 50 easily fits in the wearer's crotch, and a sense of discomfort during wearing can be suppressed. The center 51CL of the constricted portion 51 in the front-rear direction L may be located on the front side of the center 10CL of the absorbent article 10 in the front-rear direction L. The effect of shortening the length of the absorber in the width direction W on the front side of the absorbent article 10 is easily obtained.
