PROBLEM TO BE SOLVED: To provide an absorbent sheet for pets capable of surely generating color reaction by a pH discriminating part without being affected by a hydrophobic raw material containing pH ink.SOLUTION: An absorbent sheet for pets includes: a liquid-permeable surface sheet; a liquid-impermeable back surface sheet; and an absorbent body of which both surfaces are wrapped by a crepe paper and interposed between the surface sheet and the back surface sheet. In this absorbent sheet, there are provided a plurality of color reaction parts formed on the crepe sheet of the surface sheet side or the back surface sheet side and formed of functional inks for exhibiting the function by wetting, and a pH discriminating part interposed between the two color reaction parts without having a forming layer formed of functional inks or formed a liquid introduction part in which thickness of the forming layer formed of functional inks is thinner than that of the surrounding. |
