Piezoelectric vibrator, method of manufacturing piezoelectric vibrator, oscillator, electronic equipment and radio-controlled timepiece

A method of manufacturing a piezoelectric vibrator, which includes a tuning fork type piezoelectric vibrating reed that includes a pair of vibration arm portions, a package that accommodates the piezoelectric vibrating reed, and a getter material that is formed along a longitudinal direction of the vibration arm portions in an inner portion of the package, the method comprising:

• a first gettering process comprising activating a middle portion of the getter material adjacent to center portions of a longitudinal direction of the vibration arm portions;
• and
• a second gettering process comprising activating an end portion of the getter material,
• such that a cross-sectional area of a middle portion of the getter material adjacent to a center portion of the longitudinal direction of the vibration arm portion is greater than that of an end portion of the getter material.
