In an actuator using a piezoelectric element of a film having a piezoelectric substance with the thickness of less than 100 [mu]m, the electrostatic capacity of the piezoelectric element is large, and then the flowing current is large, and the prior art cannot fully decrease current consumption. A piezoelectric element drive circuit includes a piezoelectric element that has a piezoelectric substance whose thickness is 0.05 [mu]m to 20 [mu]m and two electrodes which interpose the piezoelectric substance therebetween, an inductor that is connected to the piezoelectric element in parallel, and a drive voltage generation circuit that applies a drive voltage including an AC component to the piezoelectric element and the inductor.
