PROBLEM TO BE SOLVED: To provide a method of manufacturing a piezoelectric vibrator which reduces manufacturing cost by improving the productivity and yield in manufacturing the piezoelectric vibrator. SOLUTION: The piezoelectric vibrator has been manufactured by a process of cleaning a piezoelectric blank plate; process of vapor-depositing an excitation electrode on the main surface of the blank plate after cleaning; process of adjusting the thickness of the metal electrode provided on the piezoelectric blank plate; process of dividing the piezoelectric blank plate into singular pieces after adjusting the thickness of the metal electrode to form piezoelectric vibration pieces; process of mounting each of the piezoelectric vibration pieces on a package for piezoelectric vibrator via a conductive adhesive; process of drying the conductive adhesive after mounting; and process of minutely adjusting the main vibration frequency of each of the piezoelectric vibrators after drying.
