Abstract

See full text

Disclosed is an absorbent article including a projecting-and-depressed sheet (10) as a constituent member, the absorbent article having a longitudinal direction and a width direction orthogonal to the longitudinal direction. The projecting-and-depressed sheet (10) has a plurality of depressions (3) and projections (4) on a skin-facing surface to be brought into contact with the wearer's skin. In a given direction, a movable range of an apex (40a) of the projection (4) of the projecting-and-depressed sheet (10) is 30% or greater to the length (L2) of a bottom portion of the projection (4). On the skin-facing surface of the projecting-and-depressed sheet (10), the mean friction coefficient MIU in the longitudinal direction (X) is 0.3 or less, and a difference in friction coefficient between a forward path and a return path when moved back and forth along the longitudinal direction (X) is less than 0.1. The projecting-and-depressed sheet (10) has a work of compression of 2.0 mN·cm/cm2 or greater and a compression recovery rate of 40% or greater.
