Provided is an underpants-type wearable article that has leg openings through which legs can easily pass, and that can be provided with a bulge at a buttock-covering part for covering the buttocks. An underpants-type wearable article (10) has a region (75) corresponding to the buttocks, and a pair of leak-proof cuffs having first cuff elastic bodies (57a) and second cuff elastic bodies (57b). The region corresponding to the buttocks has a buttock-covering part (78) that is surrounded by an innermost rear-waist elastic body (80), elastic bodies (76) corresponding to the buttocks, and the second cuff elastic bodies. The tensile stress at a prescribed width of the elastic bodies corresponding to the buttocks and the tensile stress at a prescribed width of the elastic region due to the second cuff elastic bodies is lower than the tensile stress at a prescribed width of the elastic region due to the innermost rear-waist elastic body.【課題】足をレッグ開口に通しやすく、臀部カバー部に膨らみを持たせて臀部を覆うことができるパンツ型の着用物品の提供。【解決手段】着用物品（１０）は、臀部対応域（７５）と、第１カフ弾性体（５７ａ）及び第２カフ弾性体（５７ｂ）を有する一対の防漏カフを含み、前記臀部対応域は、最内側後ウエスト弾性体（８０）、臀部対応弾性体（７６）及び前記第２カフ弾性体に囲まれた臀部カバー部（７８）を有し、前記臀部弾性部の所定幅における伸長応力及び前記第２カフ弾性体による弾性域の所定幅における伸長応力は、前記最内側後ウエスト弾性体による弾性域の所定幅における伸長応力よりも低い。【選択図】図２
