Abstract
A piezoelectric vibrator having excellent shock resistance and high reliability is offered. The centers of first and second piezoelectric vibrating plates are supported by pillars on a main surface of an enclosure and nearly or substantially parallel to the main surface of the enclosure. Spacers having a Young's modulus of less than 2 GPa are mounted on both end sides of the second piezoelectric vibrating plate to prevent contact between the vibrating plates, thus preventing damage. Other spacers are mounted on the main surface of the enclosure in positions corresponding to the first-mentioned spacers to prevent contact with the main surface of the enclosure, thus preventing damage to the second piezoelectric vibrating plate.
