The present invention provides a support for supporting an absorbent article attached to the abdomen of an animal from the dorsal side of the animal, wherein the absorbent article does not easily contract in the front-back direction of the animal even if the animal moves during the attachment of the support and the absorbent article, and animal excrement does not easily leak to the outside. In a plane view, this support (1) has a first direction (D1) corresponding to the direction (DS) around the animal abdomen when put on and a second direction (D2) orthogonal to the first direction (D1) and corresponding to the front-back direction (DF) of the animal when put on. Additionally, the support has affixing parts (13, 14) extending in the second direction (D2) at each of the end parts (15, 16) in the first direction (D1) and detachably affixing one end part in the longitudinal direction (L) of the absorbent article. Each of the affixing parts (13, 14) has a length (A) in the second direction equal to or greater than the length (B) of an absorbent body (23) for the absorbent article in the direction of width.本發明，係用以從動物的背部側支撐裝著於動物腹部之吸收性物品的支撐體，目的為提供一種於支撐體與吸收性物品之裝著時，即使動物移動之情況，亦難以使吸收性物品在動物的前後方向上收縮，可使動物的排泄物難以朝向外部漏出的支撐體。本發明的支撐體(1)，於俯視觀察下，具備有：於裝著時與動物的腰圍方向(DS)對應之第1方向(D1)、及與上述第1方向(D1)正交且於裝著時與動物的前後方向(DF)對應之第2方向(D2)，並且於上述第1方向(D1)之兩端部(15、16)的各個中，具備有：將延伸於上述第2方向(D2)且裝卸自如地在吸收性物品的長邊方向(L)之一方的端部予以固定的固定部(13、14)，各個上述固定部(13、14)，係具備有上述吸收性物品的吸收體(23)的寬幅方向長度(B)以上的第2方向長度(A)。
