PROBLEM TO BE SOLVED: To provide an absorption sheet for a pet from which an absorbent does not spill out even when part of the absorption sheet for a pet is cut, and of which cut part can be used, thereby being highly useful.SOLUTION: An absorption sheet for a pet includes: a liquid-permeable surface material 21; a liquid-impermeable back surface material 22; an absorbent 31; an absorbing part 3 constituted by wrapping the absorbent 31 between the surface material 21 and the back surface material 22; and an extension part 2 provided by extending the surface material 21 and the back surface material 22 wrapping the absorbent 31 so as to surround the absorbing part 3, where multiple absorbing parts are aligned while being mutually connected at end parts of the extension parts.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2020,JPO&INPIT【課題】ペット用吸収シートの一部分をカットしても吸収材がこぼれず、カットした一部分を使用することができる利便性の高いペット用吸収シートを提供すること。【解決手段】透液性の表面材21と、不透液性の裏面材22と、吸収材31と、を備え、表面材21と裏面材22との間に吸収材31を包んで構成される吸収部3と、吸収材31を包む表面材21と裏面材22とが延出して該吸収部3を囲うように設けられた延長部2と、を備え、複数の吸収部が、延長部の端部を互いに接続して配列されていることを特徴とするペット用吸収シート。【選択図】図3
