PROBLEM TO BE SOLVED: To improve touch to a skin in a part positioned in an end part of a leg opening in an exterior body.SOLUTION: The problem is solved by an underpants-type disposable wearing article which includes: an exterior body 12F, 12B which has three or more sheet layers in a lower end part 80 in a wing region J and a non-joined part 87 where at least one of an innermost layer 84 and an outermost layer 85 is not joined to an inner sheet layer 86 overlapped with the back of the sheet layer； the non-joined part 87 which continues in a width direction WD in a range including a region between a lower end part elastic member 83 in a lowermost position and a lower edge in the wing region J in a front-back direction LD； a gap, between at least one of the innermost sheet layer 84 and the outermost sheet layer 85 and the inner sheet layer 86 overlapped with the back of the sheet layer, which is closed at both sides in the front-back direction LD of the non-joined part 87； and lower end part gatherings UG where the lower end part 80 in the wing region J contracts in the front-back direction LD by the contraction of the lower end part elastic member 83.SELECTED DRAWING: Figure 13COPYRIGHT: (C)2020,JPO&INPIT【課題】外装体における脚開口の端部に位置する部分の肌触りを改善する。【解決手段】上記課題は、外装体１２Ｆ，１２Ｂのウイング領域Ｊの下端部８０は三層以上のシート層を有するとともに、最も内側のシート層８４及び最も外側のシート層８５の少なくとも一方とその裏に重なる内部シート層８６とが接合されていない非接合部８７を有し、非接合部８７は、最も下方に位置する下端部弾性部材８３とウイング領域Ｊの下縁との間の領域を含む前後方向ＬＤ範囲で幅方向ＷＤに続いており、最も内側のシート層８４及び最も外側のシート層８５の少なくとも一方とその裏に重なる内部シート層８６との隙間は、非接合部８７の前後方向ＬＤの両側で閉じられており、下端部弾性部材８３の収縮によりウイング領域Ｊの下端部８０が前後方向ＬＤに収縮し、下端部ギャザーＵＧが形成されている、ことにより解決される。【選択図】図１３
