The purpose of the present invention is to provide a technology whereby excrement can be effectively absorbed, in an absorbent sheet for pets. [Solution] An absorbent sheet (100) for pets, having a fluid-permeable surface sheet (110), a fluid-impermeable rear surface sheet (130), and an absorbent body (150) that absorbs fluid that has penetrated the surface sheet (110). The absorbent sheet (100) for pets is characterized by: the surface sheet (110) being configured so as to receive pet excrement, in a state in which the rear surface sheet (130) is placed in a placement location； the absorbent body (150) being formed by a surface-side covered sheet (161), a rear surface-side covered sheet (163), and an absorbent layer (170)； and the absorbent layer (150) being bonded by an adhesive (180) across the entire surface of at least one of either the surface-side covered sheet (161) or the rear surface-side covered sheet (163).
