Claims

[Scope of utility model registration request]

A resonant plate to which a piezoelectric element is attached is supported at its primary resonance peripheral portion by thin seating surfaces formed at the front ends of annular pedestals provided opposite from the case body and the case lid, The side wall of the case lid extends from the outer periphery of the base of the pedestal, and the front end of the pedestal has a thin, annular seating surface opposite to the thin, annular seating surface formed at the front end of the pedestal that also serves as a side wall protruding from the case body. and a pedestal of the case body, the piezoelectric resonator is characterized in that a concave groove is formed to allow an adhesive to flow into the base of the case body to strengthen the bond between the two.
