PURPOSE:To enable precise frequency adjustment, by using the part other then electrodes opposing each other for the vibrator as the frequency adjusting region. CONSTITUTION:The lead 2a of the electrode 2 of the vibtator 1 is taken as the frequency region, and the frequency adjustment body 6 consisting of conductor or dielectric substance is provided on it with evaporation or coating means. If the frequency error is negative to the objective frequency due to excessive amount of the frequency adjustment body 6, a given amount of the frequency adjustment body 6 is sputtered with laser beam to increase the frequency of the oscillator to objective frequency. Further, the frequency adjustment body 6' can be provided for either one surface of electrodes of the vibrator 1' and the part other than the lead. |
