Both high air permeability and high peeling strength are achieved.

The above problem is solved by providing an underpants-type disposable diaper including a stretchable region (80) stretchable at least in one direction in an outer body (20), in which the stretchable region (80) is formed by stacking an elastic film (30) between a first sheet layer (20A) composed of a nonwoven fabric and a second sheet layer (20B) composed of a nonwoven fabric, and in a state in which the elastic film (30) is stretched in the stretching and contracting direction, the first sheet layer (20A) and the second sheet layer (20B) are joined via through holes (31) formed in the elastic film (30) at a large number of sheet bond portions (40) arranged at intervals in each of a stretching and contracting direction and a direction orthogonal thereto, and in the sheet bond portions (40), the first sheet layer (20A) and the second sheet layer (20B) are joined at least by a melted and solidified material (30m) of the elastic film (30) among the first sheet layer (20A) and the second sheet layer (20B).

A disposable absorbent article may include a chassis that includes a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet; and a leg gasketing system and a waist gasketing element. The leg gasketing system may include an inner cuff and an outer cuff; the inner cuff may include an inner cuff folded edge and an inner cuff material edge and the outer cuff may include an outer cuff material edge such that the web of material is folded outward to form the inner cuff folded edge. When tested by the Blowout Method Test as described herein, the disposable absorbent article has a Blowout Percent Leakage of less than about 9.0%.

The present invention is intended to provide an absorbent article that is excellent in anti-odor effect at the time of disposal. A pants-type disposable diaper includes an anti-odor tape that has a first gas barrier layer coupled to the pants-type disposable diaper and a second gas barrier layer that is stuck in a separable manner to either front or back surface of the first gas barrier layer via an adhesive agent containing an anti-odor agent. The anti-odor tape takes an anti-odor measure by separating the second gas barrier layer from the first gas barrier layer to expose the adhesive agent to the outside at the time of disposal of the pants-type disposable diaper.

An underpants-type disposable diaper wherein the end portions of elastic members are kept from being drawn in, and the bonding strength in side sealed portions is kept from deteriorating. The diaper has outer member defining front and back body sections, wherein side portions of the outer member in the front and back body sections are joined to form side sealed portions, which produce a waist opening and a pair of leg openings. The front and/or back body sections, are provided with a tortuous elastic member extending with curvature from one to the other of the side sealed portions, and bonded thereto with adhesive. The amount of adhesive applied to a zone neighbouring the inner zone of each side sealed portion is larger than that applied to the outer zone of each side sealed portion.
