Abstract

PURPOSE:To reduce the crystal impedance and to increase the shock resistance, by constituting the thickness at the circumference as in a specific range of the total thickness of the oscillator. CONSTITUTION:The oscillator is constituted that the ratio of the center of oscillation piece (total thickness of oscillator t) to the circumference of oscillator (remained thickness of oscillator tO) is 0.2-0.6. Thus, the crystal impedance R1 can be reduced and the shock resistance can be increased. Then, even if the oscillator is made small, the crystal impedance R1 can be suppressed smaller. Thus, miniature size of thickness slip oscillator excellent in electric performance can be obtained.
