A compressed groove point (16) where compressed grooves (12) formed bilaterally and symmetrically on both sides of a center line (CL) in a lengthwise direction of a sanitary napkin (1) or lines extended from center lines of the compressed grooves (12) intersect with each other at a position corresponding to a front end (31) of a intergluteal cleft of a wearer is formed, and a right and left pair of outline inflection points (17) is formed in an outline of a rear end of the sanitary napkin (1) formed into a bilateral and symmetric wavelike shape. Easy deformation parts (18) that facilitate generation of a deformation in a transverse direction of the sanitary napkin (1) and are formed of the compressed grooves that become base edges of the deformation, are provided on or in the vicinity of two virtual lines (S) connecting the compressed groove base point (16) to the outline inflection points (17) on right and left sides, respectively, such that a distance between the two virtual lines (S) gradually increases toward a rea side.
