Panty-style sanitary napkins

Abstract

The present invention addresses the need for a panty-type sanitary napkin configured to allow the user to easily determine the position of the crotch stretch area overlapping with the crotch elastic member during wear. The panty-type sanitary napkin (1) has a top sheet (10) covering the skin side of the absorbent core material and contacting the wearer, and a pair of side sheets (12) covering the outer sides of the top sheet in the width direction. At the center of the absorbent body (2) in the width direction, a crotch stretch area (R27) is provided, which stretches forward and backward by means of a crotch elastic member (27) positioned closer to the non-skin side than the absorbent core material. The top sheet (10) is disposed in the crotch stretch area. When viewed from the skin side of the panty-type sanitary napkin, the color of the area with the side sheets (R12) is different from the color of the area with the top sheet (R10).
