摘要： A piezoelectric driving device includes a piezoelectric vibrating body and a driving circuit. The piezoelectric vibrating body includes a contact which extends in a first direction and comes into contact with a driven member, a first piezoelectric element which generates bending vibration in a direction intersecting with the first direction in accordance with a first driving voltage, and a second piezoelectric element which generates longitudinal vibration in the first direction in accordance with a second driving voltage. The piezoelectric vibrating body is configured such that a resonance frequency of the longitudinal vibration is higher than a resonance frequency of the bending vibration. The driving circuit sets a driving frequency of each of the first driving voltage and the second driving voltage to be equal to or higher than the resonance frequency of the longitudinal vibration.
