1. An absorbent article comprising a topsheet including a projecting-and-depressed region, a backsheet, and an absorbent member arranged between the topsheet and the backsheet, 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:
a plurality of slanting projections are formed in the projecting-and-depressed region;
the slanting projections project toward the wearer's skin side, and a position of an apex of each of the slanting projections is deviated toward one side in the longitudinal direction from a central position located between both ends of the slanting projection in the longitudinal direction;
in the projecting-and-depressed region, a first sheet and a second sheet which are layered on one another are joined together at a plurality of joined portions, and the first sheet forms the slanting projections that project in a direction separating from the second sheet at sections other than the joined portions;
the topsheet includes, as densified portions in the projecting-and-depressed region,
first joined portions formed by fusion-bonding the first sheet and the second sheet by embossing, and
second joined portions formed by fusion-bonding the first sheet and the second sheet by embossing; and
a periphery of each of the slanting projections is surrounded by the first joined portions and the second joined portions each having a shorter length, in the longitudinal direction, than the first joined portion;
wherein the slanting projections have a laterally-oblong planar-view shape in which a length, in the width direction, of the slanting projections is longer than a length thereof in the longitudinal direction.
