<p>PROBLEM TO BE SOLVED: To provide a piezoelectric vibrator capable of obtaining a stable frequency characteristic while restraining vibration hindrance due to distortion applied to a fastening part of a piezoelectric vibration piece.SOLUTION: The piezoelectric vibrator comprises: a crystal vibration piece 10 having a vibration part 12 on both main faces 15, 17 of which excitation electrodes 16, 18 are formed, and a base part 13 on both main faces 15a, 17a of which extraction electrodes 16a, 18a communicated with the vibration part 12 and extracted from the excitation electrodes 16, 18 are respectively formed; and a base 21 to which the crystal vibration piece 10 is fastened. The extraction electrodes 16a, 18a of the crystal vibration piece 10 are formed along an outer periphery of the crystal vibration piece 10 in a plane view. One extraction electrode 18a is fastened to the base 21 via a fastening member 30 almost at a center of an outer peripheral part 19 in a Z-axis direction crossing with an X-axis direction at the base part 13, and the other extraction electrode 16a is fastened to the base 21 via a wire 40.</p> |
