される。(Example) An aluminum layer is formed on one surface of a polymer film by a vapor deposition method, and the aluminum layer is masked with a resist agent according to a conductor pattern. After performing the mask treatment, the polymer film having the aluminum layer formed thereon is dipped in a solution of acid or alkali to dissolve and remove the aluminum layer other than the mask portion to form a conductor pattern on one surface of the polymer film. Then, a ceramics layer is formed by electrolytic deposition. A conductor pattern is used as an anode in an aqueous solution of sodium aluminate 30 g / as an electrolytic solution, an iron plate is used as a cathode, and is immersed in the electrolytic solution, and a direct current is continuously applied while maintaining the anode current density at 1 A / dm 2 . By applying an electric current for 20 minutes, a ceramic layer of aluminum oxide having a thickness of 4 to 5 μm is formed on the surface of the aluminum conductor pattern.
