ABSTRACT:
A mechanical vibrator for a timepiece in which a ceramic supporting substrate is rigidly secured to an inner wall of an evacuated housing. The supporting substrate is formed at its one surface with a pair of conducting metal layers serving as leads and at its other surface with a conducting metal layer over a substantially large area. A piezoelectric vibrating element having exciting electrodes is placed on the ceramic supporting substrate and rigidly connected thereto such that the electrodes of the piezoelectric vibrating element are electrically connected to the conducting metal layers formed on the one surface of the ceramic supporting substrate. The conducting metal layers are in turn connected to projecting leads extending outwardly of the evacuated housing and adapted to be connected to a printed circuit of the timepiece.
