Absorbent article

An absorbent article comprising a projecting-and-depressed sheet as a constituent member, the absorbent article having a longitudinal direction that corresponds to a front-rear direction of a wearer and a width direction that is orthogonal to the longitudinal direction, wherein:

• the projecting-and-depressed sheet has a plurality of depressions and projections 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 of the projection of the projecting-and-depressed sheet is 30% or greater to a length of a bottom portion of the projection;
• on the skin-facing surface of the projecting-and-depressed sheet, a mean friction coefficient MIU in the given direction 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 given direction is less than 0.1;
• the projecting-and-depressed sheet has a work of compression of 2.0 mN·cm/cm2 or greater and a compression recovery rate of 40% or greater;
• the projecting-and-depressed sheet is a composite sheet including a first sheet and a second sheet that are layered on one another and that are joined together at a plurality of joined portions, wherein the joined portions are flat;
• the first sheet forms the projections that project in a direction separating from the second sheet at sections other than the joined portions;
• the projection's outer peripheral length, in the given direction, along the projection's surface within a cross section in a thickness direction of the projecting-and-depressed sheet is at least 1.2 times the length, in the given direction, of the bottom portion of the projection;
• and
• a length between respective apexes of the projections adjacent to one another in the given direction is from 0.5 to 5 times a depth of the depression located between those projections;
• the first sheet includes a first layer on the skin-facing surface side and a second layer on a non-skin-facing surface side;
• and
• the first layer and the second layer include first fibers and second fibers satisfying the following condition (3) or the following conditions (2) to (3), the second layer including a larger amount of the second fibers than the first layer, a content of the second fibers in the second layer being at least 2 times a content of the second fibers in the first layer:
• (2) a fiber diameter of the second fibers is greater than that of the first fibers;
• and
• (3) the second fibers are crimped fibers having a greater number of crimps than the first fibers.
