<p>PROBLEM TO BE SOLVED: To provide a bus bar having an insulation covering with high reliability, usable even under severe conditions in which a conductor is covered with a thin polyimide film, and a method for producing the same.SOLUTION: Provided is a bus bar coated with a polyimide film, characterized in that polyimide films having thermal fusibility are arranged at the upper face and the lower face of a planar conductor, and the conductor and the films are tightly adhered by heating under pressure. Each polyimide film having thermal fusibility suitably being a polyimide film in which at least one side of a heat resistant non-thermoplastic polyimide film is provided with a surface layer made of thermo-fusible polyimide.</p> |
