Abstract
Disclosed is a sanitary napkin including a liquid absorbent layer and a liquid-permeable topsheet covering a body surface of the liquid absorbent layer. The topsheet is joined to the liquid absorbent layer in a specific pattern. The pattern includes longitudinal join lines which extend longitudinally and are laterally spaced from each other and a connecting join line which connects the longitudinal join lines. The liquid absorbent layer has a low stiffness portion in a region enclosed by the longitudinal join lines and the connecting join line. The liquid absorbent layer has a lower stiffness in the low stiffness portion than in portions outside the longitudinal join lines.
