PURPOSE:To enable easy formation of the second sputtering film with high adherence by closely contacting a metallic material to the surface of a jig in the first sputtering when zinc oxide films are formed on two sides of the material. CONSTITUTION:In the first sputtering of metallic material 6, by applying a press. one side to be subjected to the second sputtering is closely contacted to jig 10 to make airtightness. By this method zinc oxide films can easily be formed on two sides of material 6 by repeating sputtering twice, and a piezoelectric oscilltor having superior electrical performance, or the lke can be manufactured. |
