PROBLEM TO BE SOLVED: To prevent an opening of an end part on a crotch side in an exterior body.SOLUTION: A front side exterior body 12F and a rear side exterior body 12B are apart in a back and forth direction. The front side exterior body 12F and the rear side exterior body 12B have a non-stretchable area A1 provided in the middle in a width direction and a stretchable area A2 provided on both sides in the width direction in the non-stretchable area A1 in a back and forth direction range having an absorber 56. The non-stretchable area A1 has: an inside sheet layer 12H and an outside sheet layer 12S following the stretchable area A2 and an unnecessary elastically stretchable member 19 composed of either an uncut part left between the inside sheet layer 12H and the outside sheet layer 12S that follows the elastic stretchable member of the stretchable area A2 or a cut piece of the elastically stretchable member that does not continue the elastically stretchable member of both the stretchable areas A2. On the crotch side of the unnecessary elastically stretchable member 19, there is a welded part 23 where the inside sheet layer 12H and the outside sheet layer 12S are welded.SELECTED DRAWING: Figure 9COPYRIGHT: (C)2017,JPO&INPIT【課題】外装体における股間側の端部の開口を防止する。【解決手段】上記課題は、前側外装体12F及び後側外装体12Bが前後方向に離間され、前側外装体12F及び後側外装体12Bは、吸収体56を有する前後方向範囲に、幅方向中間に設けられた非伸縮領域A1と、この非伸縮領域A1の幅方向両側に設けられた伸縮領域A2とを有し、非伸縮領域A1は、伸縮領域A2から連続する内側シート層12H及び外側シート層12Sと、これら内側シート層12H及び外側シート層12S間に残された、伸縮領域A2の弾性伸縮部材から連続する切断残部、及び両方の伸縮領域A2の弾性伸縮部材と連続しない弾性伸縮部材の切断片の少なくとも一方からなる不要弾性伸縮部材19とを有し、不要弾性伸縮部材19の股間側に、内側シート層12H及び外側シート層12Sが溶着された溶着部23を有している、ことにより解決される。【選択図】図9
