Problems solved by technology

[0004] However, in the absorbent article described in Document 1, since the upper layer of the absorbent body is not embossed, if the upper layer absorbs liquid, the upper layer collapses, and the fit to the excretory part of the wearer cannot be sufficiently improved.
[0005] In addition, since the absorbent article described in Document 2 does not have embossed recesses formed on the portion corresponding to the excretion portion, the absorber also collapses at the portion corresponding to the excretion portion as in Document 1. fit
In addition, in the absorbent article described in Document 2, if the embossed concave portion is also provided on the absorbent body corresponding to the excretory portion, the flexibility of this portion will be impaired.

Abstract

The absorbent article 1 of the present invention includes a skin abutting surface 2, a non-skin abutting surface 3 and an absorber 4 interposed between both of the surfaces. The absorber 4 includes a layered part 40 where an upper absorption layer 41 and a lower absorption layer 42 are layered, and the upper absorption layer 41 is positioned on the side of the skin abutting surface. The layered part 40 of the absorber 4 is constituted in such a way that the apparent density of the lower absorption layer 42 is lower than that of the upper absorption layer 41 under loading of 0.5g / cm<2>, and the apparent density of the lower absorption layer 42 is not lower than that of the upper absorption layer 41 under loading of 20g / cm<2>.
