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.
