Abstract

The invention provides a slender napkin for physiology capable of increasing a function for preventing menstrual blood from leaking rearward by fitting it to an anal cleft part and enabling its rear portion to retain a curved state. This napkin (1) for physiology comprises a surface component (3) formed of a liquid permeable surface sheet (23) covering a liquid absorbing layer (22). The surface component (3) is raised from the skin side surface of a napkin body (2) by the elastic force of an elastic member (36) to form a raised part (31) having a front end (34) and a rear end (35). The raised part (31) is fitted into the anal cleft part to prevent the menstrual blood from leaking rearward.
