Patent

CA 2299961

There is disclosed an absorbent article including: a surface structure having a liquid-permeable surface sheet located on a liquid-receiving side; a back sheet; and an absorbent core sandwiched between the surface structure and the back sheet. In an area including at least a centerline extending in a longitudinal direction of the absorbent article, the surface sheet is corrugated to form recesses and ridges extending in the longitudinal direction and alternating with each other in a transverse direction perpendicular to the longitudinal direction. The ridges are given an elastically shrinking function in the longitudinal direction at least at their crests or vicinities thereof so that the surface structure is formed into a curved shape. The surface structure thus curved can fit the shape of a crotch. Therefore, the liquid is hard to flow in the transverse direction to prevent the leakage.
