A method of manufacturing a piezoelectric vibrator comprises forming a gettering metal film on a surface of a piezoelectric vibrator piece and forming a frequency-adjusting weight, separate from the gettering metal film, on the piezoelectric vibrator piece. The piezoelectric vibrator piece is then placed in a hermetic container after which the hermetic container is hermetically sealed. 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 frequency-adjusting weight to adjust the frequency of vibration of the piezoelectric vibrator piece.
