PROBLEM TO BE SOLVED: To provide an absorption main body for an animal excreta disposer which allows the easy attachment of the absorption main body to a belt body before the attachment of the animal excreta disposer, and makes the absorption main body and the belt body hardly come off from each other in the attachment of the animal excreta disposer.SOLUTION: An absorption main body 5 for an animal excreta disposer having a belt body 3 which is attached along a periphery of a body of an animal, and the absorption main body 5 arranged along the back, crotch and abdomen of the animal and fixed to the belt body 3 comprises fixed parts 19, 21 which are fixed to the belt body 3 at least at either of a back-side end part 7 and a body-side end part 9 in a plane view in a deployed state. The absorption main body also has an absorption main body center region 39 extending to a longitudinal direction L, and a pair of absorption main body side part regions 41 which are partitioned by a pair of virtual lines VS extending to the longitudinal direction L from both the end parts of the fixed parts 19, 21 in a width direction W. A pair of the absorption main body side part regions 41 are formed so as to be prevented from adhering to the fixed parts 19, 21 even if a pair of the absorption main body side part regions are turned up toward the absorption main body center region 39.SELECTED DRAWING: Figure 6【課題】本開示は、動物排泄物処理具の装着前に吸収本体を帯体に取り付け易く、動物排泄物処理具の装着中に吸収本体と帯体とが外れ難い、動物排泄物処理具用の吸収本体を提供する。【解決手段】動物の胴周りに沿って装着される帯体３と、動物の背部、股下部及び腹部に沿って配置され、帯体３に対して固定される吸収本体５とを備えた動物排泄物処理具用の吸収本体５は、展開した状態の平面視にて、背部側端部７及び腹部側端部９の少なくとも一方において、帯体３に固定される固定部１９、２１を備え、固定部１９、２１の幅方向Ｗにおける両端部から長手方向Ｌに延びる一対の仮想面ＶＳにより区画された長手方向Ｌに延びる吸収本体中央領域３９と一対の吸収本体側部領域４１とを有し、一対の吸収本体側部領域４１が吸収本体中央領域３９に向かってめくれても固定部１９、２１に付着することが抑制されるように、一対の吸収本体側部領域４１が構成されている。【選択図】図６
