Abstract: PURPOSE:To avoid deterioration of characteristics caused by depolarization even if a high electric field is applied by a method wherein electrodes are provided on both sides of the polarizing direction of a piezoelectric slipping effect type actuator element and the voltage of a driving source is applied to those electrodes through a bridge of diodes which are so selected as to give the element the same electric field as the field of polarization. CONSTITUTION:A driving source 30 consists of a function generator which generates optional waveforms and a DC amplifier whose maximum generating voltage is + or -200V. Two terminals of the driving source 30 are connected to electrodes 22 and 23 provided on the two main surfaces of a piezoelectric slipping effect type actuator 11 and the X-terminal and the Y-terminal of a bridge circuit which is connected to the driving source 30 in parallel with the actuator terminals 22 and 23 and constituted by diodes 51-54 are so arranged as to have always (+) potential and (-) potential respectively. Therefore, even if a high voltage is applied to the element, the reduction of the displacement can be avoided.
