Claims preview

1 . An electrode comprising: a polarizable electrode layer; a non-polarizable electrode layer laminated on the polarizable electrode layer; and a conductive gel layer laminated on the non-polarizable electrode layer such that the conductive gel layer is configured to contact a skin surface, wherein the non-polarizable electrode layer comprises a silver and silver chloride layer laminated on the polarizable electrode layer, and a corrosion prevention layer covering the silver and silver chloride layer, wherein the corrosion prevention layer is made of a polymer-based corrosion inhibitor and has a thickness of 0.015 m to 0.5 m, wherein the corrosion inhibitor comprises at least one compound selected from a polyester-based resin, a urethane-based resin, an acrylic resin, an epoxy-based resin, a melamine-based resin, a cellulose-based resin, or combinations of two or more thereof, and wherein the corrosion prevention layer is configured to be ion-permeable such that ion exchange occurs between the silver and silver chloride layer and the conductive gel layer. 2 . The electrode according to claim 1 , wherein the corrosion inhibitor comprises a thermosetting agent. 3 . The electrode according to claim 2 , wherein the thermosetting agent comprises an isocyanate-based thermosetting agent.
