An underpants-type disposable diaper has outer members that separately or integrally configures a front body and a back body. An inner member is attached to the outer members from the front body to the back body. The outer members have a waist extended section that extends to a side of the waist opening of an edge of the inner member on a waist side. The underpants-type disposable diaper further has a display sheet containing a liquid impervious resin film on an outer side of the inner member in a region in which the outer members and the inner member overlap with each other in at least one of the front body and the back body, in which the display sheet extends from a region overlapping the inner member into the waist extended section.
