Abstract
In a piezoelectric vibrator having a center supporting piezoelectric vibrating reed, one edge of an almost rectangular piezoelectric vibrating reed is fixed at two places of a case by a comparatively hard conductive adhesive. Also, the other edge facing the above-mentioned one edge is fixed at two other places of the case by a comparatively soft adhesive. Further, the case and a lid to cover the piezoelectric vibrating reed which constitute a container for the piezoelectric vibrator are sealed using a glass material having a low melting point of 340° C. or less. Further, in the case of a cantilever supporting piezoelectric vibrating reed, stoppers made of soft adhesive are formed at the top and bottom of the other edge facing the above-mentioned one edge with a slight clearance being provided.
