An object of the present invention is to facilitate the manufacture of an elastic structure using an elastic member. In the stretchable structure including the elastic member 19 provided between the first sheet layer 12S and the second sheet layer 12H, the stretchable region extends from one end to the other end in the stretchable direction of the stretchable structure. 22 and the non-stretchable region 21 are alternately repeated three or more regions, and both ends in the stretch direction are stretchable regions 22, and the elastic member 19 is attached to the first sheet layer 12S and the first sheet layer 12S at both ends of the stretchable region 22 in the stretch direction. 2 has an adhesive region of the hot melt adhesive 71 adhered to the sheet layer 12H, and in an unfolded state, the distances 71d between the adhesive regions adjacent to each other in the expansion / contraction direction are all the same, and are positioned at both ends in the expansion / contraction direction of the expansion / contraction structure. This is solved by the fact that the double of the stretch direction length 71w of the bonding region to be performed and the stretch direction length 71w of the adhesive region located at the end of the stretch region 22 on the non-stretch region 21 side are all the same.[Selection] Figure 18【課題】弾性部材による伸縮構造の製造を容易にする。【解決手段】上記課題は、第１シート層１２Ｓ及び第２シート層１２Ｈの間に設けられた弾性部材１９とを備えた伸縮構造において、伸縮構造の伸縮方向の一端から他端まで、伸縮領域２２及び非伸縮領域２１が交互に３領域以上繰り返し、かつ伸縮方向の両端が伸縮領域２２となっており、伸縮領域２２の伸縮方向の両端部に、弾性部材１９が第１シート層１２Ｓ及び第２シート層１２Ｈに接着されたホットメルト接着剤７１の接着領域を有し、展開状態で、伸縮方向に隣り合う接着領域の間隔７１ｄがすべて同じであり、伸縮構造の伸縮方向の両端部に位置する接着領域の伸縮方向長さ７１ｗの２倍と、伸縮領域２２における非伸縮領域２１側の端部に位置する接着領域の伸縮方向長さ７１ｗとがすべて同じであることにより解決される。【選択図】図１８
