A stretchable structure for absorbent article, comprising: a sheet-like member that is composed of one air permeable material and has a plurality of pleats arranged at intervals so as not to overlap in a fallen state and inter-pleat portions overlapping in the state in which the pleats are fallen; and elongated resilient and elastic members provided between opposing surfaces of the pleats along a longitudinal direction of the pleats, wherein the opposing surfaces of the pleats are continuously or intermittently joined in the longitudinal direction of the pleats such that the opposing surfaces of each pleat are not separated at least at a base portion of the pleat, outer surfaces of the pleat are not joined to the inter-pleat portions except for at both longitudinal ends of the pleats, resilient and elastic members are arranged in the pleats at a tip-side with regard to the base portion and at least both ends of the resilient and elastic members are fixed between the opposing surfaces of the pleats, the pleats and the inter-pleat portions are contracted by contraction of the resilient and elastic members, the pleat protrude to a side opposite to a skin-contact-side, and inter-pleat portions overlap the skin-side of the pleats in the fallen state.
