Claims

[Scope of utility model registration request]

A piezoelectric vibrator consisting of a piezoelectric element and a diaphragm housed in the inner bottom surface of the case body is provided with an annular side wall that comes into contact with the diaphragm of the piezoelectric vibrator at the end of the fitting with the inner peripheral surface of the side wall of the case body. In a case that is sealed by a case lid and has a pair of terminal pieces that contact the piezoelectric element and the diaphragm, respectively, pulled out, either one of the inner peripheral surface of the side wall of the case body and the outer peripheral surface of the side wall of the case lid. or a piezoelectric buzzer characterized in that an axial groove is carved in both, and an adhesive is introduced through the groove and cured.
