There is provided a sanitary napkin (1) in which a convex portion (20) of an absorbent body that is high toward a skin side is formed at a skin side surface of the absorbent body (4) at a center portion in a width direction. The convex portion (20) is constituted by a front convex portion (24) designed to be provided at an area including a body fluid expelling portion of a wearer, a rear convex portion (25) designed to be provided at an area including an intergluteal cleft of the wearer, and a constricted convex portion (23) provided at an area connecting the front convex portion (24) and the rear convex portion (25) in a front-rear direction of a napkin whose both side edges are constricted toward an inner side. In particular, the rear convex portion (25) is designed to be provided at an area from a start position of the intergluteal cleft of the wearer at a crotch side, in a rearward direction, to a position exceeding the intergluteal cleft, an end position of the intergluteal cleft or at a middle position of the intergluteal cleft, the maximum width of the rear convex portion (25) being 20 to 36 mm, and the maximum width of the rear convex portion (25) and the width of the front convex portion (24) being the same width.
