The tacky hydrogel is a tacky hydrogel comprising a polymer matrix comprising a copolymer of a monofunctional monomer and (a) a crosslinkable monomer, and other polymer components, water, and a polyhydric alcohol, wherein the monofunctional hydrogel Wherein at least one of the structural unit derived from a monomer and the above other polymer component is at least one selected from the group consisting of (b) an ethylenic unsaturated carboxylic acid, an ethylenic unsaturated carboxylate, and an ethylenic unsaturated carboxylic acid having a hydroxyl group, an acid group, a salt thereof, an amino group, and / An unsaturated carboxylic acid derivative, and the other polymer component (c) includes a polymer compound having an oxyalkylene group or a side chain having a polyoxyalkylene group. |
