Abstract
A base plate containing aluminum as a main component and an electrically conductive counter plate are bonded together through the medium of an electrically conductive adhesive. Even when an oxide film is formed on the surface of the base plate, electrical continuity between the base plate and the counter plate, which are connected together through the medium of the electrically conductive adhesive, is improved by a process of applying a resistance lowering voltage, which reduces the resistance component due to the oxide film by causing a dielectric breakdown.
