Abstract

PURPOSE:To eliminate an oscillating capacitor in an IC, by forming a capacitor through the provision of electrodes at a part of a case which is evacuated or sealed with glass, and a quartz oscillator used for wrist watch and the like with glass, ceramic or metal. CONSTITUTION:A quartz oscillator bar 11 is contained in a quartz case 10, a part of which is clipped with capacitor electrodes 12a, 12b which forms a capacitor by taking the quartz case between them as a dielectric substance. A part 13 is evacuated or sealed with glass. The effect of humidity can be avoided by implanting the electrode 12a in the case 10 and exposing only a part of the electrode 12a. Further, the electrode 12b can be implanted in the case 10 for laminated layer. The capacitor can also be formed by clipping a ferrodielectric thin film in the case 10. The capacitor incorporated with the quartz oscillator is prevented for the change in static capacitance due to humidity change, and the oscillating capacitor in the IC can be omitted by adjusting the oscillating frequency by the quartz oscillator itself.
