Claim Text:
1. An electrode device used in iontophoresis treatment, comprising a substrate, a medication reservoir layer, a main-electrode layer and a sub-electrode layer, wherein the medication reservoir layer containing ionized medication is placed in contact with a skin, and an electric current is applied to the medication reservoir layer through the main-electrode layer to perform the iontophoresis treatment, wherein: the main-electrode layer and the sub-electrode layer are secured on the substrate, wherein the sub-electrode layer is insulated from the main-electrode layer and holds the medication reservoir layer on the substrate; the medication reservoir layer is located on the substrate, so as to be in contact with the main-electrode layer and the sub-electrode layer; the medication reservoir layer is a gel containing halogen compound, and the sub-electrode layer comprises a metal having a lower ionization tendency than hydrogen; and the medication reservoir layer and the sub-electrode layer are bonded to each other, wherein the bonding of the medication reservoir layer and the sub-electrode layer is effected by applying an electric current to the medication reservoir layer and the sub-electrode layer, to thereby hold the medication reservoir layer on the substrate while the medication reservoir layer is in contact with the main-electrode layer.
