An object of the present invention is to provide a stretchable structure which has a high stress relaxation property, has elasticity, and returns slowly after elongation, has a small feeling of tightening, and has a fit. The surface of a core layer (Y) containing a resin composition (X) containing a 4-methyl-1-pentene / α-olefin copolymer (A) satisfying the following requirement (a) is heated. An elastic structure in which a surface layer (Z) containing a plastic elastomer (C) is laminated. Requirement (a): The copolymer (A) is derived from a structural unit (i) derived from 4-methyl-1-pentene and an α-olefin (however, excluding 4-methyl-1-pentene). Assuming that the total of the structural unit (ii) and the structural unit (ii) is 100 mol%, the structural unit (i) includes 50 to 90 mol% and the structural unit (ii) 10 to 50 mol%.
