A disposal diaper () improves breathability by laminating a folded portion () and an opposing portion () to form a first waist circumferential region (), which is an upper portion of a waist circumferential region (). A second waist circumferential region () below the first waist circumferential region is formed by laminating the folded portion, an end sheet (), a second exterior sheet (), and the opposing portion, and a second waist elastic member () 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 () in the waist circumferential region.

Pants-type absorbent article

A pants-type disposable diaper includes a pair of strip projecting parts projecting laterally from a line of connection between front and rear parts located respectively on the belly and back sides of a wearer, a first waist elastic member joined to a first waist region that is an upper part of a waist region extending along a waist opening, and a second waist elastic member joined to a second waist region that is a lower part of the waist region. In a state in which an outer covering sheet is elongated in a right-left direction, a first unit contractile force that is a contractile force in the right-left direction per unit width of the first waist region in an up-down direction is smaller than a second unit contractile force in the second waist region.
