付着片２２ａ，２２ｂの各張出し部２５，２６の中前腹部２ｃに面する側の面（内面側）には、付着部２７，２８がそれぞれ設けられ、本体部２４の内面側にも付着部２９が設けられている。これらの付着部２７〜２９は、第２付着部に相当するものであり、中前腹部２ｃに設けられた付着部２３に対して着脱自在に付着するようになっている。 Adhering portions 27 and 28 are respectively provided on the surfaces (inner surface side) of the sticking pieces 22a and 22b facing the middle front abdominal portion 2c, and the sticking portions 22a and 22b are also provided on the inner surface side of the main body 24. 29 is provided. These adhering portions 27 to 29 correspond to second adhering portions, and are detachably attached to the adhering portion 23 provided in the middle front abdominal portion 2c.

付着部２３の具体例としては、表面に微細なループ構造が密に形成された不織布、織布、編み物等を有するループ材が考えられ、付着部２７〜２９の具体例としては、そのループ材に着脱自在に係合する微細なフック構造が表面に密に形成されたフック材が考えられる。さらに具体的には、付着部２３としては、例えば、面ファスナーのループ材として好適に用いられる不織布、織布等を表面に有するプラスチックフィルム複合材が用いられる。付着部２７〜２９としては、面ファスナーのフック材として好適に用いられる表面に密に形成されたピンを有するプラスチックフィルムが用いられる。あるいは、ループ材を別部材として中前腹部２ｃに貼着するのではなく、中前腹部２ｃの外面側を表面処理してループ材（付着部２３）として機能させるようにしてもよい。 As a specific example of the adhering portion 23, a loop material having a nonwoven fabric, a woven fabric, a knitted fabric or the like in which a fine loop structure is densely formed on the surface is conceivable. As a specific example of the adhering portions 27 to 29, the loop material is considered. A hook material in which a fine hook structure that is detachably engaged with the surface is formed densely on the surface is conceivable. More specifically, as the attachment portion 23, for example, a plastic film composite material having a nonwoven fabric, a woven fabric, or the like suitably used as a loop material of a hook-and-loop fastener on the surface is used. As the adhering portions 27 to 29, a plastic film having pins densely formed on the surface preferably used as a hook material of a hook-and-loop fastener is used. Or you may make it function as a loop material (attachment part 23) by surface-treating the outer surface side of the middle front abdominal part 2c instead of sticking to the middle front abdominal part 2c as another member.

また、付着部２３の他の具体例としては、粘着剤との繰り返し剥離性を有するように表面処理、例えばピーロイル加工されたプラスチックフィルム等が考えられ、付着部２７〜２９の他の具体例としては、繰り返し利用可能な接着剤などが考えられる。 Further, as another specific example of the adhesion part 23, a plastic film or the like which has been subjected to surface treatment, for example, a pyroyl process so as to be repeatedly peelable from the adhesive, can be considered. An adhesive that can be used repeatedly can be considered.

なお、前記の付着部２３及び付着部２７〜２９の前記２つの具体例において、付着部２３側の構成と付着部２７〜２９側の構成を入れ替えてもよい。 In the two specific examples of the attaching part 23 and the attaching parts 27 to 29, the structure on the attaching part 23 side and the structure on the attaching parts 27 to 29 side may be interchanged.

また、本実施形態では、各付着片２２ａ，２２ｂの本体部２４における張出し部２５，２６間の中間位置には、分割ラインに相当する切込み３０が設けられている。この切込み３０は、本体部２４の自由端側から左右方向に沿って本体部２４の一部を所定寸法だけ切り込むことにより形成されている。この切込み３０によって、止着時における付着片２２ａ，２２ｂを用いた各張出し部２５，２６の止着位置等の自由度が拡大される。なお、変形例として、切込み３０は、本体部２４を上下に完全に分断するように形成されていてもよく、付着部２９、左前腹部２ａ及び右前腹部２ｂにまで及んでいてもよい。 Moreover, in this embodiment, the notch 30 equivalent to a dividing line is provided in the intermediate position between the overhang | projection parts 25 and 26 in the main-body part 24 of each adhesion piece 22a, 22b. The cut 30 is formed by cutting a part of the main body 24 by a predetermined dimension along the left-right direction from the free end side of the main body 24. By this cut 30, the degree of freedom such as the fastening position of the overhang portions 25 and 26 using the attached pieces 22 a and 22 b at the time of fastening is expanded. As a modification, the notch 30 may be formed so as to completely divide the main body portion 24 vertically, and may extend to the attachment portion 29, the left front abdominal portion 2a, and the right front abdominal portion 2b.

また、付着片２２ａ，２２ｂの各張出し部２５，２６の先端部は、付着片２２ａ，２２ｂをつまみやすくするために、つまみ部３１（図４参照）となっている。このつまみ部３１には、付着部２７，２８は設けられていない。 Further, the tip portions of the overhang portions 25 and 26 of the adhering pieces 22a and 22b form a knob portion 31 (see FIG. 4) in order to make it easier to pinch the adhering pieces 22a and 22b. The knob portion 31 is not provided with the attachment portions 27 and 28.

このような構成により、右側の付着片２２ｂの張出し部２５，２６をつまんで付着片２２ｂの付着部２７〜２９を付着部２３から引き剥がし、右方向外方に引っ張ると、図３に示すように、右破断部１７ｂが破れて、右前腹部２ｂが付着片２２ｂと一体となって右側に展開する。同様に、左側の付着片２２ａの張出し部２５，２６をつまんで付着片２２ａの付着部２７〜２９を付着部２３から引き剥がし、左方向外方に引っ張ると、図４に示すように、左破断部１７ａが破れて、左前腹部２ａが付着片２２ａと一体となって左側に展開する。このとき、中前腹部２ｃは股部４と接合された状態に保たれ、前股部４ａの外側に残ることになる。 With such a configuration, when the protruding portions 25 and 26 of the right attached piece 22b are pinched and the attached portions 27 to 29 of the attached piece 22b are peeled off from the attached portion 23 and pulled outward in the right direction, as shown in FIG. In addition, the right breaking portion 17b is torn and the right front abdominal portion 2b is unfolded on the right side together with the adhering piece 22b. Similarly, when the protruding portions 25 and 26 of the left attached piece 22a are pinched and the attached portions 27 to 29 of the attached piece 22a are peeled off from the attached portion 23 and pulled outward leftward, as shown in FIG. The broken portion 17a is torn and the left front abdominal portion 2a is integrated with the adhering piece 22a to expand on the left side. At this time, the middle front abdominal part 2c is kept in a state of being joined to the crotch part 4, and remains outside the front crotch part 4a.

このため、この使い捨てパンツ１は、図１に示すように、破断部１７ａ，１７ｂを破断する前の製品出荷時の状態では、前腹部２と股部４とが接合部分１８によって固定されているため、パンツとして機能し、付着片２２ａ，２２ｂ等の開閉手段のない通常の使い捨てパンツと同様に容易に上げ下げできるようになっている。また、この状態では、仮に付着片２２ａ，２２ｂと付着部２３との係合が外れても、前腹部２と股部４とが別々になってしまうことがない。 For this reason, as shown in FIG. 1, in the disposable pants 1, the front abdomen 2 and the crotch part 4 are fixed by the joint part 18 in a state at the time of product shipment before the breaking parts 17 a and 17 b are broken. Therefore, it functions as a pant and can be easily raised and lowered in the same manner as a normal disposable pant without opening and closing means such as the attached pieces 22a and 22b. Further, in this state, even if the attachment pieces 22a, 22b and the attachment portion 23 are disengaged, the front abdominal portion 2 and the crotch portion 4 are not separated.

また、この使い捨てパンツ１がパンツ状態で着用させている場合において、後述する吸収体４３が排泄物を吸収、保持した場合には、付着片２２ａ，２２ｂの係合を解除して、破断部１７ａ，１７ｂを破断して展開して、パンツ１を着用者から容易に取り除くことができる。この場合、着用者の衣服を脱がさなくとも、パンツ１の取外しができる。 Further, when the disposable pants 1 are worn in the pants state, when the absorber 43 described later absorbs and holds the excrement, the engagement of the attachment pieces 22a and 22b is released, and the fracture portion 17a is released. , 17b can be broken and expanded to easily remove the pants 1 from the wearer. In this case, the pants 1 can be removed without taking off the wearer's clothes.

また、装着片２２ａ，２２ｂの係合を解除して破断部１７ａ，１７ｂを破断し、前腹部２を展開して、パンツ１の内部の汚染状況を確認した後、装着片２２ａ，２２ｂを付着部２３に係合させて、パンツ１を元のパンツ状態に戻すことができる。また、このパンツ１と尿取りパット等の補助パットとを併用しているときにも、装着片２２ａ，２２ｂを着脱して補助パットの交換等を容易に行うことができる。 Further, the engagement of the mounting pieces 22a and 22b is released, the breaking portions 17a and 17b are broken, the front abdomen 2 is expanded, and the contamination inside the pants 1 is confirmed, and then the mounting pieces 22a and 22b are attached. By engaging with the part 23, the pants 1 can be returned to the original pants state. Even when the pants 1 and an auxiliary pad such as a urine pad are used in combination, the auxiliary pads can be easily exchanged by attaching and detaching the mounting pieces 22a and 22b.

また、着用させる前に、パンツ１を図５に示す状態に展開しておいて着用者の臀部にあてがって、図４、図３、図１の順に閉じてゆくことにより、このパンツ１を通常の使い捨ておむつのように利用することもできる。この場合、着用者の衣服を脱がさなくとも、パンツ１の着用及び取り外しができる。 Moreover, before putting it on, the pants 1 are normally deployed by unfolding the pants 1 in the state shown in FIG. 5, placing them on the wearer's buttocks, and closing them in the order of FIGS. 4, 3, 1. It can also be used like a disposable diaper. In this case, the pants 1 can be worn and removed without taking off the wearer's clothes.

＜股部＞
股部４は、図５に示すように、全体形状としては展開すると前後方向に延びる略帯状の形態を有し、前股部４ａ、後股部４ｂ、及びそれらの中間に位置する中股部４ｃを備え、主に中股部４ｃを中心として着用者の股間部にあてがわれる。前股部４ａは、図５ないし図７に示すように、中前腹部２ｃの内面側に重ね合わされた状態で接合部分１８によって中前腹部２ｃと接合されている。後股部４ｂは、図５に示すように、後背部３の内面側に重ね合わされた状態で後背部３と接着固定されている。このような股部４の左縁部１６ａ及び右縁部１６ｂには、脚用弾性部材４０ａ，４０ｂが縁部１６ａ，１６ｂの延設方向に伸張された状態で取り付けられている。 <Crotch>
As shown in FIG. 5, the crotch portion 4 has a substantially band-like shape that extends in the front-rear direction when deployed as a whole, and includes a front crotch portion 4 a, a rear crotch portion 4 b, and a middle crotch portion located between 4c, and is mainly applied to the crotch part of the wearer centering on the middle crotch part 4c. As shown in FIGS. 5 to 7, the front crotch portion 4 a is joined to the middle front abdominal portion 2 c by the joining portion 18 in a state of being superimposed on the inner surface side of the middle front abdominal portion 2 c. As shown in FIG. 5, the back crotch portion 4 b is bonded and fixed to the back portion 3 in a state of being overlapped with the inner surface side of the back portion 3. Leg elastic members 40a and 40b are attached to the left edge 16a and the right edge 16b of the crotch part 4 in a state of being extended in the extending direction of the edges 16a and 16b.

股部４は、透液性のトップシート４１と不透液性のバックシート４２との間に、吸収体４３を挟み込んで構成されている。吸収体４３は、所定の横幅を有し、中股部４ｃを中心にして前後方向に帯状に広がっている。股部４の内面側における吸収体４３の左右両側には、股部４の延設方向に沿って延びる起立部４４ａ，４４ｂが設けられている。 The crotch portion 4 is configured by sandwiching an absorbent body 43 between a liquid-permeable top sheet 41 and a liquid-impermeable back sheet 42. The absorber 43 has a predetermined lateral width and spreads in a belt shape in the front-rear direction with the middle crotch 4c as the center. On both the left and right sides of the absorbent body 43 on the inner surface side of the crotch portion 4, standing portions 44 a and 44 b extending along the extending direction of the crotch portion 4 are provided.

例えば、トップシート４１は透液性の不織布等により構成され、バックシート４２は撥水性不織布等により構成される。また、吸収体４３は、例えば、粉砕したパルプ繊維やセルロース繊維等の親水性繊維集合層に粒状の高分子吸収体を混合した塊をティッシュペーパーなどの紙シート又は透液性不織布シート等の被覆シートで包み、所定形状に成形されたものである。 For example, the top sheet 41 is composed of a liquid-permeable nonwoven fabric or the like, and the back sheet 42 is composed of a water-repellent nonwoven fabric or the like. The absorbent body 43 is, for example, a paper sheet such as tissue paper or a liquid-permeable non-woven sheet coated with a mass obtained by mixing a granular polymer absorbent body with a hydrophilic fiber aggregate layer such as pulverized pulp fiber or cellulose fiber. Wrapped in a sheet and molded into a predetermined shape.

トップシート４１及びバックシート４２の吸収体４３と重ならない部分は、互いに対向する面同士が接着剤、例えばホットメルト接着剤によって互いに接合されている。より好ましくは、図８に示すように、トップシート４１の横幅は、吸収体４３の肌面側を覆い、かつバックシート４２の横幅よりも若干狭く設定され、トップシート４１の吸収体４３を超えて前後左右に張り出した部分が、接着剤、例えばホットメルト接着剤によりバックシート４２と接合されている。バックシート４２におけるトップシート４１の左右両側に張り出した部分の肌面側には、起立部４４ａ，４４ｂを構成する左右のサイドシート４５ａ，４５ｂが接着剤、例えばホットメルト接着剤によって接合されている。 The portions of the top sheet 41 and the back sheet 42 that do not overlap with the absorber 43 are bonded to each other by an adhesive, for example, a hot melt adhesive. More preferably, as shown in FIG. 8, the width of the top sheet 41 is set to cover the skin surface side of the absorber 43 and slightly narrower than the width of the back sheet 42, and exceeds the absorber 43 of the top sheet 41. The portions that protrude from front to back and from side to side are joined to the back sheet 42 by an adhesive, for example, a hot melt adhesive. Left and right side sheets 45a and 45b constituting upright portions 44a and 44b are joined to the skin surface side of the portion of the back sheet 42 that protrudes from the left and right sides of the top sheet 41 by an adhesive, for example, a hot melt adhesive. .

また、サイドシート４５ａ，４５ｂの前後方向の両端縁は、股部４の前後方向の両端縁に接着剤６０、例えばホットメルト接着剤により接合されている。サイドシート４５ａ，４５ｂの左右方向内方側縁部は、前後方向に伸びる弾性部材４６を包み込むようにして、封止部４７にて熱溶着（又は超音波溶着）等により固定されている。起立部４４ａ，４４ｂは、弾性部材４６の収縮力によりその左右方向内方側縁部が縮められ、これによって図８に示すように着用者の肌に押し付けられる方向に起立する。 Further, both end edges in the front-rear direction of the side sheets 45a, 45b are joined to both end edges in the front-rear direction of the crotch portion 4 by an adhesive 60, for example, a hot melt adhesive. The inner side edges of the side sheets 45a and 45b are fixed by heat welding (or ultrasonic welding) or the like at the sealing portion 47 so as to wrap around the elastic member 46 extending in the front-rear direction. The standing portions 44a and 44b are erected in the direction in which the inner side edge portion in the left-right direction is contracted by the contraction force of the elastic member 46, and thereby pressed against the skin of the wearer as shown in FIG.

また、本実施形態では、図５に示すように、股部４における前腹部２及び後背部３の腰回り部３ａと重なる重複部分において、左右の縁部を傾斜辺４８ａ，４８ｂ，４９ａ，４９ｂとし、その横幅を前後方向の端縁側に向けて徐々に減少させている。 Moreover, in this embodiment, as shown in FIG. 5, in the overlapping part which overlaps with the waist part 3a of the front abdominal part 2 and the back part 3 in the crotch part 4, the right and left edges are inclined sides 48a, 48b, 49a, 49b. The lateral width is gradually reduced toward the edge in the front-rear direction.

この傾斜辺４８ａ，４８ｂにより、使い捨てパンツ１を上げ下げする際に、前股部２ａが引っ掛かってめくれたり、折れ曲がったり、着用者の肌に影響を及ぼすのを防止し、スムーズに上げ下げすることができる。 The inclined sides 48a, 48b can prevent the front crotch portion 2a from being caught and turned up, bent, or affected on the wearer's skin when the disposable pants 1 are raised and lowered, and can be raised and lowered smoothly. .

また、通常、後背部３と股部４とが重なる領域については、後背部３の収縮力が弱まる傾向にあるが、前記傾斜辺４９ａ，４９ｂによるトリム領域を形成することにより、後背部３の伸縮部分の面積が後背部３の上側に向けて徐々に増えてゆき、これによって後背部３が着用者の後背部にフィットしやすくなる。 Usually, in the region where the back portion 3 and the crotch portion 4 overlap, the contraction force of the back portion 3 tends to be weakened. However, by forming the trim region by the inclined sides 49a, 49b, The area of the stretchable portion gradually increases toward the upper side of the back portion 3, and this makes it easier for the back portion 3 to fit the back of the wearer.

なお、股部４の構成の変形例として、吸収体４３をシート４１，４２の間に挟み込むのではなく、吸収体４３をシート４２の肌面側に貼着し、シート４１を省略する構成としてもよい。あるいは、吸収体４３の前後の端部にシートを接合したものを股部４として用いるようにしてもよく、大型の吸収体４３を用いてその吸収体４３を股部４として用い、シート４１，４２を省略するようにしてもよい。 As a modified example of the configuration of the crotch portion 4, the absorbent body 43 is not sandwiched between the sheets 41 and 42, but the absorbent body 43 is attached to the skin surface side of the sheet 42, and the sheet 41 is omitted. Also good. Or what joined the sheet | seat to the front-and-back edge part of the absorber 43 may be used as the crotch part 4, the absorber 43 is used as the crotch part 4 using the large sized absorber 43, and the sheet | seat 41, 42 may be omitted.

＜後背部＞
後背部３は、図３ないし図６に示すように、展開すると略矩形の左右下側の角を略斜めに切り落としたような形態を有し、着用者の背面側の腰回り部から臀部にかけた部分にあてがわれる。このため、この後背部３は、着用者の背面側の腰回り部に主に位置する平面視略横長帯状の腰回り部３ａと、その腰回り部３ａの下側に連なり着用者の臀部に主に位置する平面視略台形状の臀部３ｂとを備えている。腰回り部３ａの上縁部１３には、ウエスト用弾性部材５１が左右方向に伸張された状態で取り付けられており、腰回り部３ａのそれ以外の領域には、ボディ用弾性部材５２が左右方向に伸張された状態で取り付けられている。後背部３の左斜め下の傾斜状の縁部１５ａには、脚用弾性部材５３ａが縁部１５ａに沿って伸張された状態で取り付けられており、後背部３の右斜め下の傾斜状の縁部１５ｂには、脚用弾性部材５３ｂが縁部１５ｂに沿って伸張された状態で取り付けられている。これらの弾性部材５１，５２，５３ａ，５３ｂの収縮、伸張により後背部３が着用者の後背部及び臀部にフィットしやすくなっている。 <Back part>
As shown in FIGS. 3 to 6, the back portion 3 has a form in which the left and right lower corners of a substantially rectangular shape are cut off obliquely when unfolded, and is hung from the waist portion on the back side of the wearer to the buttocks. It is applied to the part. For this reason, this back part 3 is connected to the lower part of the wearer's buttocks on the lower part of the waistline part 3a in a plan view substantially in the shape of a horizontally long belt mainly located in the waistline part on the back side of the wearer and the waistline part 3a. And a substantially trapezoidal flange portion 3b in plan view. A waist elastic member 51 is attached to the upper edge 13 of the waistline portion 3a in a state of being stretched in the left-right direction. The body elastic member 52 is disposed in the other region of the waistline portion 3a. It is attached in a stretched state. A leg elastic member 53a is attached to the inclined edge 15a diagonally to the lower left of the back portion 3 in an extended state along the edge 15a. The leg elastic member 53b is attached to the edge 15b in a state of being extended along the edge 15b. By contraction and extension of these elastic members 51, 52, 53a, and 53b, the back portion 3 can easily fit the wearer's back and buttocks.

特に、後背部３の臀部３ｂは、下側に向けて横幅が徐々に狭くなる構成とされているとともに、その左右の傾斜状の縁部１５ａ，１５ｂに脚用弾性部材５３ａ，５３ｂが設けられているため、脚用弾性部材５３ａ，５３ｂの収縮力により縁部１５ａ，１５ｂが縮められると、臀部３ｂが着用者の臀部にフィットしやすくなっている。 In particular, the collar portion 3b of the back portion 3 is configured such that the lateral width gradually decreases toward the lower side, and leg elastic members 53a and 53b are provided on the left and right inclined edges 15a and 15b. Therefore, when the edge portions 15a and 15b are contracted by the contraction force of the leg elastic members 53a and 53b, the heel portion 3b is easily fitted to the wearer's buttock.

なお、脚用弾性部材５３ａ，５３ｂは、臀部３ｂの左右の傾斜状の縁部１５ａ，１５ｂ及び下縁部１５ｃに沿って連続的に臀部３ｂに取り付けられた後、少なくとも股部４の吸収体４３と重なる部分５４（図６参照）について、弱化処理が施されている。弱化処理とは、その部分５４の弾性部材を切断したり、収縮力を弱める処理を行う等により、ノーテンション状態とすることである。これによって、脚用弾性部材５３ａ，５３ｂの収縮力によって吸収体４３に不所望な歪み等が生じ、その吸収機能が低下するのが防止される。 The leg elastic members 53a, 53b are attached to the heel part 3b continuously along the right and left inclined edges 15a, 15b and the lower edge part 15c of the heel part 3b, and then the absorber of at least the crotch part 4 A weakening process is applied to a portion 54 (see FIG. 6) that overlaps 43. The weakening process is to make a no tension state by cutting the elastic member of the portion 54 or performing a process of weakening the contraction force. This prevents an undesired distortion or the like in the absorber 43 due to the contraction force of the leg elastic members 53a and 53b, thereby preventing the absorption function from deteriorating.

また、左右の付着片２２ａ，２２ｂに上下に２股に分かれた２個の張出し部２５，２６が設けられているため、その２個の張出し部２５，２６を有効に利用してパンツ１の止着を行うことにより、パンツ１の形状や各部の締め付け力を着用者の体形に応じて微妙に調節することができ、着用者の体形へのフィット性の向上が図れる。 In addition, since the left and right attachment pieces 22a and 22b are provided with two overhanging portions 25 and 26 that are divided into two forks, the two overhanging portions 25 and 26 are effectively used to By performing the fastening, the shape of the pants 1 and the tightening force of each part can be finely adjusted according to the wearer's body shape, and the fit to the wearer's body shape can be improved.

また、左右の付着片２２ａ，２２ｂの本体部２４に設けられた切込み３０により、各付着片２２ａ，２２ｂにおける各張出し部２５，２６の止着時の止着位置等の自由度をより拡大することができ、その結果、着用者の体形へのフィット性のさらなる向上が図れる。例えば、切込み３０の間を広げるようにして、各付着片２２ａ，２２ｂの張出し部２５，２６をその上下間隔を広げて付着部２３に付着させることができる。 Further, the cuts 30 provided in the main body portion 24 of the left and right attachment pieces 22a and 22b further expand the degree of freedom of the attachment positions and the like at the time of attachment of the overhang portions 25 and 26 in the attachment pieces 22a and 22b. As a result, the fit to the wearer's body shape can be further improved. For example, the extension portions 25 and 26 of the attachment pieces 22a and 22b can be attached to the attachment portion 23 with their vertical intervals widened so that the space between the cuts 30 is widened.

また、分割ラインとして切込み３０が設けれているため、止着時にユーザがわざわざ分割ラインの破断作業等を行う必要がなく、止着作業が容易に行える。 Further, since the cuts 30 are provided as the dividing lines, it is not necessary for the user to bother to break the dividing lines at the time of fastening, and the fastening work can be easily performed.

また、付着部２３が中前腹部２ｃにおける形成領域Ａ１内に略面状に連続的に設けられているため、左右の付着片２２ａ，２２ｂを形成領域Ａ１内の任意の位置に付着させることができ、止着の態様の自由度が高い。 Moreover, since the attaching part 23 is continuously provided in the formation area A1 in the middle front abdominal part 2c in a substantially planar shape, the left and right attaching pieces 22a and 22b can be attached to arbitrary positions in the forming area A1. It is possible and the degree of freedom of the fastening mode is high.

また、付着部２３を形成する形成領域Ａ１の縦幅Ｗ１を左右の付着片２２ａ，２２ｂの縦寸法Ｌ１とほぼ等しく設定しているため、付着部２３を必要かつ十分な範囲に形成することができ、付着部２３を形成するためのコストを抑制することができる。 Further, since the vertical width W1 of the formation area A1 in which the attachment portion 23 is formed is set to be substantially equal to the vertical dimension L1 of the left and right attachment pieces 22a and 22b, the attachment portion 23 can be formed in a necessary and sufficient range. And the cost for forming the adhering portion 23 can be suppressed.

＜変形例＞
本実施形態の変形例として、付着片２２ａ，２２ｂに切込み３０を設ける代わりに、図９に示すように、ミシン目５９を設けるようにしてもよい。この場合、使い捨てパンツ１の使用時に、ユーザが付着片２２ａ，２２ｂのミシン目５９を破断するか否かを選択することができ、ユーザの要求に幅広く対応することができる。 <Modification>
As a modification of this embodiment, instead of providing the notches 30 in the attachment pieces 22a and 22b, a perforation 59 may be provided as shown in FIG. In this case, when the disposable pants 1 are used, the user can select whether or not to break the perforations 59 of the attached pieces 22a and 22b, and can respond widely to the user's request.
