Method of fabricating piezoelectric vibrator

A method of fabricating a piezoelectric vibrator comprising:

• providing 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;
• disposing a pair of excitation electrodes on two side surfaces of the piezoelectric vibrator piece for vibrating the piezoelectric vibrator piece;
• forming bond films on upper and lower surfaces of the frame;
• connecting the bond films to the excitation electrodes;
• disposing shortcircuiting electrodes on the piezoelectric oscillating plate for causing a shortcircuit to electrically connect the bond films to each other;
• and
• covering the piezoelectric vibrator piece to seal the piezoelectric vibrator piece in an airtight manner via the bond films without hampering vibration of the piezoelectric vibrator piece.

• forming bond films on the surfaces of the two sides of the vibrator;
• connecting the bond films to the excitation electrodes;
• anodically bonding each of a pair of cover members using a respective one of the bond films to a respective one of the surfaces of the two sides of the vibrator to seal the piezoelectric vibrator piece in an airtight manner without hampering vibration of the piezoelectric vibrator piece;
• and
• disposing a plurality of shortcircuiting films on the vibrator for shortcircuiting the bond films to each other.
