Abstract

A sanitary napkin includes a napkin body containing a liquid absorbent layer and a three-dimensional structure is disposed on the skin-side surface of the napkin body. The three-dimensional structure is formed of a reinforcing member and a liquid-permeable sheet, and an elastic member is disposed along an apex to extend in a longitudinal direction. The reinforcing member has high-density portions and low-density portions alternating with each other in the longitudinal direction so that the apex can be shortened in the longitudinal direction by an elastic contractive force of the elastic member. Therefore, the napkin body can be easily kept curved.
