Abstract
The present invention relates to an electrode structure, which comprises a substrate provided with an electrode formed thereon, wherein the substrate comprises a layer of a fluorine-containing polyimide and a layer of a fluorine-free resin is interposed between the polyimide layer and the electrode and, in particular, to the foregoing electrode structure, wherein the electrode comprises a gold layer as the outermost or surface layer and an aluminum layer interposed between the substrate and the gold layer. The electrode structure of the present invention never causes any peeling off of the electrode due to insufficient adhesion of the electrode to the substrate, the structure has sufficiently high strength and therefore the boundary between the substrate and the electrode formed thereon is not destroyed by the energy of ultrasonics applied thereto.
