Abstract
A sanitary napkin includes a surface element that is formed of a liquid-permeable topsheet covering a liquid absorbent layer. The surface element is raised from the skin-side surface of a napkin body by an elastic force of an elastic member to form a protuberance having a front end and a rear end. The protuberance fits in the intergluteal cleft and prevents rearward leakage of menstrual blood.
