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 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 each of the plurality of elastically stretchable members is fixed to at least one of the first sheet layer and the second sheet layer via a first hot melt adhesive at each of a pair of adhesion sites provided at an interval in the stretchable direction, wherein the first sheet layer and the second sheet layer are bonded via a second hot melt adhesive in a range at least in the stretchable direction corresponding to a space between the pair of the adhesion sites, wherein the second hot melt adhesive is an adhesive disposed intermittently in the longitudinal direction of the elastically stretchable members and continuously in a direction intersecting the elastically stretchable members, wherein the first hot melt adhesive is applied only to the outer peripheral surfaces of the elastically stretchable members, aside from the second hot melt adhesive, and wherein a holding power of the first hot melt adhesive is higher than a holding power of the second hot melt adhesive.
