To provide an absorbent underpants for improving a fear that there occurs a tendency that a front and/or rear region of an absorbent core expands outward from a front side and/or a rear side of the body of a wearer due to structural rigidity in a longitudinal direction, and as the result of this, an ugly external appearance is made, and a bulky projection possibly giving adverse effect on comfort is brought.SOLUTION: A disposable absorbent underpants 10 comprises a belt structure 20 surrounding the waist of a wearer by using front side and rear side belt parts 22,23, and an absorbent core structure 30 channel formed in the longitudinal direction. As a result of a structure channel formed during wearing due to that a channel is under at least one of the front side and rear side belt parts, further structural support for restraining an absorbent core is provided after the core absorbs liquid and is stiffened in the longitudinal direction, and a possibility of undesirable expansion at the front side and/or rear side of the underpants is reduced by elongation.SELECTED DRAWING: Figure 1 【課題】長手方向の構造的剛性によって、吸収性コアの前側及び／又は後側区域が、着用者の身体の前側及び／又は後側から外向きに膨張する傾向が生じ、その結果、見苦しい外観が作り出され、かつ快適性に悪影響を与え得る嵩高な突出部がもたらされるおそれを改善する吸収性パンツを提供する。【解決手段】前側及び後側ベルト部分２２、２３を用いて着用者の腰部を包囲するベルト構造体２０と、長手方向にチャネル形成された吸収性コア構造体３０と、を有する使い捨て吸収性パンツ１０である。チャネルは、前側及び後側ベルト部分のうちの少なくとも１つの下にあって、それにより、着用中、チャネル形成された構造体の結果として、コアが液体を吸収して、長手方向に剛化した後で、吸収性コアを拘束するための更なる構造的支持を提供し、かつパンツの前側及び／又は後側で望ましくない膨張の可能性を低減するように、伸張される。【選択図】図１
