PROBLEM TO BE SOLVED: To secure a satisfactory adhesion between a metallic oxide and a conductive film, and to improve resonance characteristics by reducing the conductor loss. SOLUTION: This manufacturing method comprises (a) making a ceramic workpiece 1 with a flat surface, (b) preparing a Zn solution which contains ions of amphoteric metals having electrochemically less noble potential than the redox potential of Zn, for instance, like Al<SP>3+</SP>or Si<SP>4+</SP>, and forming a Zn film 2 on the surface of the ceramic workpiece 1 by immersing it in the Zn solution, and then (c) forming a plating film 3 on the Zn film 2 by electroless plating.
