    Abstract: PROBLEM TO BE SOLVED: To provide a driving method for a piezoelectric vibrator which is capable of carrying out adjustment in accordance with a factor of variations in characteristics caused by deterioration of the piezoelectric vibrator after long-term use, without being accompanied by the increase in size of the device and the increase in manufacturing cost.SOLUTION: The driving method for a piezoelectric vibrator includes a driving piezoelectric element and a detection piezoelectric element formed of the same material as a material of the driving piezoelectric element, for driving the piezoelectric vibrator by applying, to the driving piezoelectric element, an alternating voltage having a frequency close to a resonance frequency of the piezoelectric vibrator. The driving method includes, in the case where it is detected based on variations in output detected from the detection piezoelectric element that at least one of variations in mechanical resistance of the piezoelectric vibrator and variations in piezoelectric characteristics of a piezoelectric element have occurred, applying an alternating voltage adjusted in accordance with the variations in mechanical resistance of the piezoelectric vibrator and/or the variations in piezoelectric characteristic of the piezoelectric element, to thereby adjust an electrical input to the piezoelectric vibrator to suppress variations in vibration amplitude of the piezoelectric vibrator.
