Abstract

PURPOSE:To secure an accurate adjustment of the frequency for the piezoelectric ceramic plate with a simple method by providing the energy enclosing electrode to the high-coupled piezoelectric plate, forming the insulating thin film on the surface of the piezoelectric cermic plate containing the electrode and then polishing or thickening the thin film. CONSTITUTION:Insulating thin film 23 is formed on the surface of one side of high- coupled piezoelectric plate 21 with energy enclosing electrde 22 formed as if film 23 covered over electrode 22. Then film 23 is polished to increase the frequency or thickened through the sputtering or other methods to lower the frequency for adjsutment. At the same time, insulating thin films 27 and 28 are formed on both surfaces of high-coupled piezoelectric electrode 25 on both surfaces of which electrode 26 is formed, and the frequency adjustment is given in the same way as mentioned above. In such way, the characteristics can be adjusted in a high accuracy for the energy enclosing type resonator or filter.
