The upper and lower layer sheets in Document 0 extend in the vertical and horizontal directions as a whole on the upper surface of the article, and the upper surface of the bat structure in contact with the lower surface of the lower layer sheet similarly extends in the vertical and horizontal directions. ing. For this reason, when the article is deformed during wearing, the upper layer sheet is likely to have wrinkles that are not preferable for absorbing body fluid. JP-A-8-117277
The upper and lower layer sheets in the literature are protruded in an arc shape in the central region of the article, but are not integrated by fusion in the central region.
As in the 060 document, if the article is deformed during wearing, the upper layer sheet is likely to have wrinkles that are undesirable for the absorption of bodily fluids.

It is preferable that the length of each side of the block 14 is 2.5 to 25 mm. If the opening diameter of the deboss 13 is less than 0.5 mm, it is difficult to obtain the integrated strength with the lower layer sheet 6b,
If it is more than 2 mm, the crushing rate of the liquid introduction opening 12 increases. If the distance between the debosses 13 is less than 2.5 mm, the arrangement of the debosses 13 is close to a linearly connected state, and the flexibility of the top sheet 6 is reduced. Is difficult to obtain, and the liquid introduction opening 12 is easily deformed. If the length of each side of the block 14 is less than 2.5 mm, the number of the blocks 14 becomes too large and the flexibility of the top sheet 6 is hindered. If the length is more than 25 mm, it is difficult to maintain the protrusion of the block 14. Become.

融着して三次元ネット状構造を形成している場合には、
その保形性に優れる。The bat structure 8 is mainly formed by forming a mixture of wood pulp fluff and superabsorbent hydrogel particles into a panel shape, and the whole is covered by a water-absorbing sheet such as tissue paper. Examples of the hydrogel include self-crosslinkable alkali metal acrylate polymers, starch graft polymers, modified cellulose, and crosslinked water-soluble polymers. The bat structure 8 made of such a material has semi-rigidity, but also has an appropriate compression restoring elasticity.
Contributes to maintaining the tension. Furthermore, when fusion with the lower layer sheet 6b is preferable, the bat structure 8 contains a heat-fusible fiber such as a polyolefin-based fiber in an amount that does not affect the absorbability, for example, up to 30% by weight. If the fibers are in the bat structure 8 and are fused together to form a three-dimensional net-like structure,
Excellent in shape retention.

高めるのに有効である。In the article according to the present invention, the central area of the upper surface protrudes in an arc shape and the upper surface is maintained in a tensioned state. The liquid introduction opening is not deformed unnecessarily and does not hinder the introduction of the body fluid into the article, which is effective in preventing the body fluid from leaking from the article. In particular, since the deboss pattern on the top sheet is formed on an imaginary line that forms a quadrangle in which a pair of corners face each other substantially in the vertical direction of the article, in other words, the arrangement of debosses on the line is in the vertical and horizontal directions. Because the block extends obliquely, even if the article is deformed in the vertical and horizontal directions while wearing it, the blocks are deformed more erratically than in the case of a grid pattern in which the arrangement of debosses only extends in the vertical and horizontal directions It is effective to enhance the above-mentioned effect without doing.
