摘要：An object is to provide a hydrogel, which is excellent in adhesiveness to anelectrode element, less reduced in tackiness and adhesiveness to an electrode elementand an object even if it absorbs water such as sweat and moisture, as well as has anoptimal adhesive force to the skin surface and gives no damage to the skin whenremoved. A hydrogel 1 having a laminate structure of layer A 10 and layer B 20, whereinlayer A 10 contains a monomer-derived component, water, a humectant, a water-insoluble polymer having tackiness and an amphiphilic polymer, the water-insolublepolymer is contained in a proportion of 3 to 20 wt% based on a total amount of layer A,and the amphiphilic polymer is a polyvinyl alcohol having a saponification degree of 50 to75% and is contained in a proportion of 0.05 to 5 wt% based on the total amount of layerA; layer B 20 contains a monomer-derived component, water and a humectant and issubstantially free of a water-insoluble polymer having tackiness and a polyvinyl alcohol;an amount of the water based on a total amount of layer B is the amount of water basedon the total amount of layer A ± 10 wt%; and an amount of the humectant based on thetotal amount of layer B is an amount of the humectant based on the total amount oflayer A ± 10 wt%.
