Abstract
A sanitary napkin in which diffusing liquid hardly reaches a rear end edge is adapted to make a liquid absorbent layer less deformable in a rear region so that it can easily be kept in close contact with the wearer's buttocks. The sanitary napkin has an elongated main absorbent region surrounded by compressed grooves that are formed in a skin-side surface. Since a rear end of the main absorbent region is far away from a rear end edge of the napkin to provide a relatively large rear region, worries about rearward leakage may be relieved. Furthermore, since auxiliary longitudinal grooves are provided in the rear region, a liquid absorbent layer may hardly be twisted.
