1. A water absorption treatment material that absorbs a liquid containing a malodorous substance, the water absorption treatment material comprising:
a plurality of a first grain that consists essentially of a porous material having an action of deodorizing the malodorous substance, the porous material being activated charcoal; and
a plurality of a second grain that contains a water-absorptive material other than the porous material as a main material,
wherein the plurality of the first grain constitutes 30% or more and 70% or less of a total amount of grains in the water absorption treatment material.
