Abstract
An absorbent article of the present invention includes an absorbent core (4) and a topsheet (2) disposed on a skin-facing surface of the absorbent core (4) and having a projecting-and-depressed structure on the skin-facing surface. The absorbent core (4) includes one or a plurality of low-basis-weight portions (41) extending in one direction and having a relatively lower basis weight than other parts of the absorbent core (4). In a plan view, the topsheet (2) includes a plurality of types of projections (24) having different sizes in an overlapping region with the low-basis-weight portions (41).
Claims8
An absorbent article comprising:
- an absorbent core;
- and
- a topsheet disposed on a skin-facing surface of the absorbent core and having a projecting-and-depressed structure on the skin-facing surface, wherein
- the absorbent article has a longitudinal direction corresponding to a front-rear direction of a wearer and a width direction orthogonal to the longitudinal direction,
- the absorbent core includes a pair of low-basis-weight portions extending in the longitudinal direction at intervals in the width direction and having a relatively lower basis weight than other parts of the absorbent core,
- in a plan view, the topsheet includes a plurality of projections having different sizes in an overlapping region with the low-basis-weight portions of the absorbent core,
- the topsheet is provided with a central region that is a center in the width direction and extends in the longitudinal direction and a pair of side regions that are adjacent to the central region and extend in the longitudinal direction,
- a length in the width direction of one of the plurality of topsheet projections provided in the central region is longer than a length in the width direction of one of the plurality of topsheet projections provided in the side regions, and
- when a width distance between center-facing inward side edges of the pair of low-basis-weight portions at the central portion in the longitudinal direction is defined as A, a width distance between center-facing inward side edges of the pair of low-basis-weight portions at the end portion in the longitudinal direction is defined as C, and a width of the central region of the topsheet is defined as B, a relation of A<B<C is established.
