PROBLEM TO BE SOLVED: To provide a structure for supporting a piezoelectric vibrator wherein a frequency is stabilized, by reducing a torsion force by adding laterally symmetrical stresses from a support plate to a piezoelectric raw plate. SOLUTION: In the structure for supporting the piezoelectric vibrator supported by the support plate where the piezoelectric raw plate is fixed with two metal terminals air-tightly passing through a metal base in order to solve the problem, an injection port of a bonding is provided on an outer side surface of thickness of the support plate, and a recessed portion which is communicated to the injection port abutted to the piezoelectric raw plate at two points in the center, is provided on an inner side surface of thickness of the support plate at the side of the piezoelectric raw plate.
