The front piece 2 and the back piece 2 include body areas 11 and 21 having side seal parts 4 formed at width-directional both end parts; and extension areas 12 and 22 having such a shape that the width in the extension width direction extending from the body areas 11 and 21 towards the crotch area 3 is gradually narrowed as it getting towards the crotch area. The body areas 11 and 21 include one or a plurality of first stretchable members 13 and 23 disposed in a stretched state along the width direction. The extension areas 12 and 22 include one or a plurality of second stretchable members 14 and 24 disposed in the stretched state along the width direction. Here, an adhesion amount of oil solution of the second stretchable members 14 and 24 is 0.1 wt.% or less. 【課題】前身頃外装体と後身頃外装体の延出領域において弾性伸縮部材が抜け易くなるという問題を改善する。【解決手段】本発明の使い捨ておむつは，前身頃１と，後身頃２と，股下域３を有する。前身頃１及び後身頃２は，サイドシール部４が幅方向の両端部分に形成された本体領域１１，２１と，本体領域１１，２１から股下域３の方向に向かって延出し幅方向における幅が股下域の方向に向かうにつれて漸次狭くなる形状の延出領域１２，２２を有する。本体領域１１，２１には，一又は複数の第１伸縮部材１３，２３が，幅方向に沿った伸長状態で配置されている。延出領域１２，２２には，一又は複数の第２伸縮部材１４，２４が，幅方向に沿った伸長状態で配置されている。ここで，第２伸縮部材１４，２４は，油剤付着量が，０．１重量％以下である。【選択図】図２
