Abstract:
An absorbent article comprising: 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,wherein, 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, and the surface structure further comprises a liquid-permeable support sheet located between the surface sheet and the absorbent core and bonded to the recesses of the surface sheet, wherein cover sheets are provided to cover longitudinally opposite end portions of the ridges, respectively and each cover sheet is dimensioned to have a transverse size larger than that of the area where the ridges are formed, and is bonded to the support sheet to open inwardly of the absorbent article.
