To provide a supporting body which supports an absorbent article attached to an abdominal part of an animal from a back part side of the animal, hardly causes the absorbent article to contract in a front-back direction of the animal when the animal moves in attaching the supporting body and the absorbent article, and hardly causes leakage of excretions of the animal to the outside.SOLUTION: A supporting body 1 includes a first direction corresponding to a waistline direction Dof an animal in attaching and a second direction which is perpendicular to the first direction and corresponds to a front-back direction Dof the animal in attaching in a plane view and has fixing parts 13, 14 which extend in the second direction at each of both end parts of the first direction and detachably fix one of end parts in longitudinal directions L1, L2 of an absorbent article. Each of the fixing parts 13, 14 has a length in the second direction greater than a length in a width direction of an absorber 23 of the absorbent article.SELECTED DRAWING: Figure 6【課題】動物の腹部に装着される吸収性物品を動物の背部側から支持するための支持体であって、支持体及び吸収性物品の装着時に動物が動いたりするような場合でも、吸収性物品が動物の前後方向に縮み難く、動物の排泄物を外部へ漏出し難くすることができる支持体を提供する。【解決手段】支持体１は、平面視にて、装着時に動物の胴周り方向ＤＳに対応する第１方向と、前記第１方向と直交し且つ装着時に動物の前後方向ＤＦに対応する第２方向とを有するとともに、前記第１方向の両端部の各々において前記第２方向に延在し且つ吸収性物品の長手方向Ｌ１、Ｌ２における一方の端部を着脱自在に固定する固定部１３、１４を有し、前記固定部１３、１４の各々は、前記吸収性物品の吸収体２３の幅方向長さ以上の第２方向長さを有する。【選択図】図６
