Patent ID: 8410861

Claim:
A method of manufacturing a piezoelectric vibrator with a piezoelectric vibrating reed accommodated therein which has a pair of vibration arm portions extending in parallel, a pair of excitation electrodes that vibrates the pair of vibration arm portions, and a mount electrode that is electrically connected to the pair of excitation electrodes, within a cavity formed between a base substrate and a lid substrate that are bonded to each other, comprising: an insulation film forming process of forming an insulation film so as to cover the excitation electrodes after producing the piezoelectric vibrating reed; a getter material forming process of forming a getter material formed of a metallic material, which improves a degree of vacuum in the cavity by being heated, in any one substrate of the base substrate or the lid substrate so as to be arranged within the cavity; and a bonding process of bonding the base substrate and the lid substrate to each other so as to accommodate the piezoelectric vibrating reed and the getter material within the cavity after mounting the piezoelectric vibrating reed on the base substrate via the mount electrode.
