Abstract
Disclosed is an absorbent article having a liquid acquisition layer between a topsheet and a liquid absorbent layer. The liquid acquisition layer is an absorbent sheet that is three-dimensionally deformed to include: longitudinal ribs projecting toward the topsheet and extending parallel with each other in a longitudinal direction of the article; and transverse ribs projecting toward the topsheet and extending in a transverse direction of the article. The transverse ribs are arranged at intervals in the longitudinal direction and connect adjacent longitudinal ribs, thereby providing a plurality of recesses surrounded by the longitudinal ribs and the transverse ribs. At least the longitudinal ribs are in contact with an overlying component, whereas bottoms of the recesses are in contact with the liquid absorbent layer.
