<p>The invention relates to simplifying wiring a piezoelectric element. A piezoelectric actuator A having an oscillator 10 that has a flat base layer 32 and piezoelectric elements 30, 31 layered to the base layer 32 and oscillates as a result of a drive signal applied to the piezoelectric elements 30, 31, and a rotor 100 driven by vibrations from the oscillator 10, is characterized by comprising a fastening part 11 for securing the oscillator 10, and lead substrates 14A, 14B that are secured to the fastening part 11 for applying a drive signal to the piezoelectric elements from a drive circuit 500 for driving the piezoelectric elements 30, 31. The lead substrates 14A, 14B have connecting parts 17A - 17C extending to the power supply electrodes 33A, 33C and detection electrode 34 disposed to the piezoelectric elements 30, 31. <IMAGE></p> |
