A disposal diaper (1) improves breathability by laminating a folded portion (46) and an opposing portion (47) to form a first waist circumferential region (407), which is an upper portion of a waist circumferential region (406). A second waist circumferential region (408) below the first waist circumferential region is formed by laminating the folded portion, an end sheet (5), a second exterior sheet (42), and the opposing portion, and a second waist elastic member (444) is joined between the folded portion and the end sheet. The folded portion has a horizontal bending resistance of 80 mm or less. This allows the second waist circumferential region to easily contract. The thickness and strength of the second waist circumferential region increase accordingly, and this makes it possible to reduce damage to an exterior sheet (4) in the waist circumferential region.
