Abstract
The surface of a signal electrode is treated as substrate treatment. An oxide film on the surface of the signal electrode is removed by roughing. The roughened surface is used as a surface treated face. A coating of fluororesin is provided on the surface treated face for lining or thermal welding to the lining material. A signal electrode is provided in the resin lining. Since the oxide film was removed from the surface of the signal electrode for roughening, the adhesive force of the coating of the fluororesin is increased. The fluororesin coating and the resin lining melt each other, and the fluororesin coating is strongly bonded to the resin lining. The adhesion between the signal electrode and the resin lining is increased without opening a hole in the signal electrode. A method uses a primer film formed by substrate treatment on the surface of the signal electrode.
