The present invention addresses the problem of preventing width direction contraction of a part in contact with an inner thigh, to prevent a deterioration in the feeling when worn and the generation of a gap. The abovementioned problem is resolved by means of a configuration in which a crossing position (C1) of a front leg-surrounding resilient member (27) and a rear leg-surrounding resilient member (26) positioned closest to an edge (29) of a leg opening is in the same position in a width direction (WD) as a side edge of a narrowest part of a narrow portion (13N) of an absorbent body (13), or in a position to the center thereof in the width direction (WD), and in which there are no resilient members other than the front leg-surrounding resilient members (27) and the rear leg-surrounding resilient members (26) in a crotch portion (28).本發明所要解決的問題在於提供一種平口褲型拋棄式尿布，其能夠防止大腿內側接觸部分在寬度方向上的收縮，從而防止穿著感的惡化或間隙的產生。 上述問題藉由下述方案得到了解決：一種平口褲型拋棄式尿布，其最靠腿開口的緣（29）側的前腿圍彈性部件（27）和後腿圍彈性部件（26）的交叉位置（C1），在寬度方向（WD）上的位置，位於與吸收體（13）的收攏部（13N）的寬度最窄的部分的側緣相同的位置處、或者比收攏部（13N）的寬度最窄的部分的側緣靠寬度方向（WD）中央側處的位置處，並且，在胯間部（28）不具有前腿圍彈性部件（27）和後腿圍彈性部件（26）以外的彈性部件。
