PROBLEM TO BE SOLVED: To eliminate the trouble of lowering in the frequency stability of a piezoelectric vibrating element caused by bent deformation of two supports erected on a metal base. SOLUTION: Concerning a piezoelectric device composed of supports 20 and 21 extended upward while respectively fixing lower parts on the upper parts of two lead members 2 and 3 air-tightly passing a metal base 1 in insulated state, longitudinal piezoelectric vibrating element 6 provided with lead electrodes 8a respectively extended from exciting electrodes 8, which are respectively formed on both main sides of a piezoelectric element plate while supporting two points of both terminals with the upper parts of respective supports, to both the left and right terminal parts of the piezoelectric element plate and the metal case, the upper parts of respective supports are respectively electrically connected with the upper terminal parts of both the lead electrodes 8a of the piezoelectric vibrating element 6 and at lower parts, bent parts 20a and 21a orthogonal with the upper parts of the respective lead electrodes 8a are fixed on the front or back of bend parts 20a and 21a at the lower parts of the respective supports.
