A stretchable structure of an absorbent article, comprising: a first sheet layer made of a nonwoven fabric; a second sheet layer made of a nonwoven fabric and opposed to one side surface of the first sheet layer; and a plurality of elongated elastically stretchable members provided along a stretchable direction at intervals from each other between the first sheet layer and the second sheet layer, wherein the first sheet layer and the second sheet layer have sheet bonded portions bonded via a hot melt adhesive disposed in a striped pattern that is intermittent in a longitudinal direction of the elastically stretchable members and continuously elongated in a direction intersecting with the elastically stretchable members; wherein the first sheet layer is made of a spunbond nonwoven fabric and the second sheet layer is made of an air-through nonwoven fabric; and wherein at intersection portions of the sheet bonded portions and the elastically stretchable members, the hot melt adhesive is continuous in the direction intersecting with the elastically stretchable members on a side of the elastically stretchable members facing the spunbond nonwoven fabric, and the hot melt adhesive is discontinuous in the direction intersecting with the elastically stretchable members on a side of the elastically stretchable members facing the air-through nonwoven fabric.
