Abstract
A piezoelectric vibrator has a piezoelectric oscillating plate having a piezoelectric vibrator piece and a frame integrally connected to a base end portion of the piezoelectric vibrator piece and surrounding the piezoelectric vibrator piece. A pair of excitation electrodes are disposed on surfaces of two sides of the piezoelectric vibrator piece for vibrating the piezoelectric vibrator piece. Bond films are formed on upper and lower surfaces of the frame and are connected to the excitation electrodes. A pair of lids seal the piezoelectric vibrator piece in an airtight manner via the bond films without hampering vibration of the piezoelectric vibrator piece. Shortcircuiting electrodes are disposed on the piezoelectric oscillating plate for causing a shortcircuiting to electrically connect the bond films to each other.
