1. A sanitary napkin comprising:
- a liquid-pervious topsheet;
a liquid-impervious backsheet; and
a liquid-absorbent core disposed between said liquid-pervious topsheet and said liquid-impervious backsheet, said sanitary napkin having a contour defined by first and second ends which extend in a transverse direction of said sanitary napkin and first and second side edges which extend continuously between said first and second ends, in a longitudinal direction of said sanitary napkin, said liquid-absorbent core being formed in a transverse middle portion thereof with a protuberant region convexly curved toward a body side of said sanitary napkin, said protuberant region being formed by bending said liquid-absorbent core substantially in an inverted V-shape along a first compressed zone which extends substantially in alignment with a longitudinal center line of said liquid-absorbent core and being concave from a lower side toward an upper side of said liquid-absorbent core, and by bending said liquid-absorbent core along a pair of second compressed zones which extend along said longitudinal direction in the vicinities of said side edges of said liquid-absorbent core and being concave from the upper side toward the lower side of said liquid-absorbent core, said liquid-absorbent core being provided on the lower side thereof with a plurality of elastic members bonded thereto under tension and obliquely extending across said first compressed zone.

Abstract
A sanitary napkin includes an absorbent core, the core being bent substantially in an inverted V-shape along a first groove provided on a lower side of the core in its transverse middle and along a pair of second grooves provided on an upper side of the core along its side edges so as to form a protuberant region being convex toward a body side of the napkin. The core is provided on its lower side with a plurality of elastic members obliquely extending across the first groove and secured to the core under tension. The napkin thus constructed does not create a feeling of discomfort against a wearer.
