PROBLEM TO BE SOLVED: To provide a piezoelectric oscillator capable of efficiently generating motive vibrating force with a small surface area. SOLUTION: The piezoelectric oscillator comprises a piezoelectric element obtained by forming electrodes 41b subjected to polarization treatment in both faces of a plate-like piezoelectric ceramic 41a, piezoelectric oscillation plates 45 having metal plates 42 bonded to one face of the piezoelectric element, and a supporting member 44 for holding the piezoelectric oscillation plates 45. The oscillator comprises a plurality of the piezoelectric oscillation plates 45 and the supporting member 44 supports two sides of a plurality of the piezoelectric oscillation plates 45 and applies input signals with the same phase to the respective piezoelectric oscillation plates 45.
