PROBLEM TO BE SOLVED: To provide an adhesive hydrogel which can prevent the so-called leaving on skin or the so-called leaving of gel, is not broken, holds good coagulation force, has controllable viscosity, and has a uniform stable structure. SOLUTION: This adhesive hydrogel is characterized by holding a polyhydric alcohol and water in the first polymer matrix and the second polymer matrix. The first polymer matrix is prepared by copolymerizing and cross-linking a non-ionic polymerizable monomer having one polymerizable carbon-carbon double bond in the molecule with a cross-linking monomer having two or more polymerizable carbon-carbon double bonds in the molecule. The second polymer matrix is prepared from a polyalkylene oxide and polyacrylic acid. COPYRIGHT: (C)2005,JPO&NCIPI
