Abstract:
1. An absorbent article, comprising an article front side portion and an article rear side portion extending on a front side and a rear side with respect to a coccyx facing portion, respectively, wherein a lower layer absorbent part and an upper layer absorbent part positioned above the lower layer absorbent part, each extend in a front-rear direction from the article front side portion to the article rear side portion, the lower layer absorbent part being configured to absorb body waste from at least a surface facing the upper layer absorbent part, and the upper layer absorbent part being configured to absorb body waste from at least a surface facing the lower layer absorbent part, the upper layer absorbent part is formed by an upper layer front side portion constituting a front side of the coccyx facing portion and an upper layer rear side portion including the coccyx facing portion on a rear side with respect to the upper layer front side portion, the upper layer front side portion is formed by a left side portion positioned on a left side with respect to a center in a wide direction and a right side portion positioned on a right side of the same; a side edge of the left side portion facing the center in the width direction and a side edge of the right side portion facing the center in the width direction, align with or come close to each other at a rear end portion, extend forward from the rear end portion with an increasing separation distance therebetween; and adapted to reach a groin part along a base of a leg of a wearer; and the lower layer absorbent part is exposed at a separation section between the side edge of the left side portion facing the center in the width direction, and the side edge of the right side portion facing the center in the width direction, the right and left side portions are fixed at side edges facing an outside in the width direction to a surface of the lower layer absorbent part; the right and left side portions are fixed to the surface of the lower layer absorbent part at front ends of portions closer to the center in the width direction than the fixed sections but are not fixed to the surface of the lower layer absorbent part at free sections other than the front end portions; and a resilient and elastic member is fixed to edges of the free sections facing the center in the width direction proximate to the interval between the right and left side portion, in a state of being stretched along the edges, these right and left side portions rise by contractile action of the tip-portion resilient and elastic member, and a clearance between the upper layer rear side portion and the lower layer absorbent part is formed as a pocket with an entrance at the separation section between the right and left side portions of the upper layer front side portion.
