The invention is to provide an electrode structure of an iontophoresis device and a method of producing the same, excellent in an economical property, an operational property, stability and safety. The electrode structure for the iontophoresis device comprises a backing having a substrate film ( 1 ) having a molding portion, an anode side and a cathode side electrode layers ( 14 ), ( 15 ) formed passing the outer circumferential portion from the inner bottom of the molding portion, and an insulating layer 3 formed in the outer circumferential portion of the molding portion. The molding portion of the backing has a dent portion and an anode side and a cathode side conductive layers ( 12 ), ( 13 ) are separately installed therein. A cover member ( 8 ) is installed to seal between these conductive layers ( 12 ), ( 13 ) and the insulating layer ( 3 ). An adhesive sheet ( 10 ) for attachment to the skin is provided to the rear face of the substrate film ( 1 ) and a liner ( 16 ) for the adhesive sheet is provided on the cover member ( 8 ).
