PROBLEM TO BE SOLVED: To accurately mount a piezoelectric element on a base. SOLUTION: In the piezoelectric vibrator where the piezoelectric element is housed in a package comprising the base and a cover, an electrode pattern for positioning is formed to the piezoelectric element. Image processing is employed to recognize and position the piezoelectric element and the base to mount the piezoelectric element on the base. The positioning electrode pattern formed to the piezoelectric element is used to recognize and position the piezoelectric element.
