PROBLEM TO BE SOLVED: To provide an underpants type absorbent article which is excellent in fitting to the skin, the inner surface and the outer surface of which are both soft and excellent touch, and the structure of which is not easily destroyed when it is put on.SOLUTION: With respect to an exterior body 11 in a ventral side part A, when a waist area A2 in which an outer layer sheet 12, an inner layer sheet 13 and an auxiliary sheet 15 overlap is divided into four in a longitudinal direction Y into an upper end area D, a middle area E of two center areas, and a lower end area F, an inner side elastic member 71 is disposed at least between the inner layer sheet 13 and the auxiliary sheet 15 in the middle area E. The joined area ratio between the auxiliary sheet 15 and the inner layer sheet 13 or an absorbent body 10 is higher in the upper end and lower end areas D and F than in the middle area E, and there is a non-joined area R2 between the inner and outer layer sheets 13 and 12. The auxiliary sheet 15 is positioned such that the lower end is within a range of 5-80 mm in the thigh direction from the edge of the absorbent body 10 in the longitudinal direction, and is joined to the absorbent body 10 for a length of 5-50 mm in the longitudinal direction.COPYRIGHT: (C)2013,JPO&INPIT【課題】肌に対するフィット性に優れている上に、内面及び外面の何れもが柔軟で肌触りが良く、しかも履き上げ時に吸収性物品の構造破壊が生じにくいパンツ型吸収性物品を提供する。【解決手段】腹側部Aにおける外装体11は、外層シート12、内層シート13及び補助シート15が重なっている胴回り領域A2を縦方向Yに4等分して上端領域D、中央2領域の中領域E及び下端領域Fに区分したときに、少なくとも中領域Eにおける内層シート13と補助シート15との間に内側弾性部材71が配され、上端及び下端領域D,Fは、補助シート15と内層シート13又は吸収性本体1との接合面積率が、中央域Eよりも高く、内外層シート13,12間に非接合領域R2を有し、補助シート15は、下端が吸収性本体10の縦方向端部から股部方向に5~80mmの範囲内に位置し、かつ縦方向における5~50mmの長さに亘って吸収性本体10と接合されている。【選択図】図3
