A pant-type diaper (1) is characterized by being provided with: a ventral member (11); a dorsal member (12); a crotch member (5) that connects both members; left and right leg openings (13, 14) that are formed by bonding the left ends (15a, 15b) and the right ends (15c, 15d) of the ventral member (11) and the dorsal member (12), thereby enclosing the left and right leg openings (13, 14) by the ventral member (11), the dorsal member (12) and the crotch member (5); and waist-surrounding elastic bodies (21, 21a, 21b) that extend leftwards and rightwards from the ventral member (11) and the dorsal member (12), and that are disposed in a region below lumbar parts (4, 4a, 4b) along the upper edges of both members (11, 12) and above the left and right leg openings (13, 14). The pant-type diaper (1) is further characterized by the tightening force of at least some of the waist-surrounding elastic bodies (21, 21a, 21b) gradually weakening from the lumbar parts (4, 4a, 4b) towards the left and right leg openings (13, 14).
