Abstract
A method of manufacturing a piezoelectric vibrator comprises providing a piezoelectric vibrator piece inside a hermetic container. A gettering metal film is formed inside the hermetic container on an inner surface of the container or on a surface of the piezoelectric vibrator piece, and a weight is formed separate from the metal film on the piezoelectric vibrator piece. A laser beam is irradiated on the metal film to heat the same to getter gas contained inside the hermetic container, and after completion of gettering, the laser beam is irradiated on the weight to adjust the frequency of vibration of the piezoelectric vibrator piece.
