Abstract
A piezoelectric actuator A has an oscillatorthat has a flat base layerand piezoelectric elementslayered on the base layerand oscillates as a result of a drive signal applied to the piezoelectric elements, and a rotordriven by vibrations from the oscillator. The piezoelectric actuator A includes a fastening partfor securing the oscillator, and lead substratesA,B that are secured to the fastening partfor applying a drive signal to the piezoelectric elements from a drive circuitfor driving the piezoelectric elements. The lead substratesA,B have connecting partsA–C extending to the power supply electrodesA,C and a detection electrode
