To prevent deterioration of appearance of pleats due to unintended adhesion. A stretchable structure of an absorbent article includes: a first sheet layer (12S) made of a nonwoven fabric； a second sheet layer (12H) made of a nonwoven fabric and opposed to one side of the first sheet layer (12S)； and a plurality of elongated elastically stretchable members (19) provided along the stretchable direction at intervals from each other between the first sheet layer (12S) and the second sheet layer (12H). The first sheet layer (12S) and the second sheet layer (12H) have sheet bonded portions (70) bonded via a hot melt adhesive disposed in a striped pattern that is intermittent in the longitudinal direction of the elastically stretchable members (19) and continuously elongated in the direction intersecting with the elastically stretchable members (19), either one of the first sheet layer (12S) and the second sheet layer (12H) is made of a spunbond nonwoven fabric, and the other sheet layer is made of an air-through nonwoven fabric whose surface on the spunbond nonwoven fabric side is a fluffy surface.
