A device includes a first set of switches and a second set of switches; a first filter and a second filter each comprising an unfiltered terminal and a filtered terminal; and a first piezoelectric element and a second piezoelectric element each comprising a first contact and a second contact. Turning on the first set of switches and turning off the second set of switches applies a first driving voltage to the first piezoelectric element and applies a second driving voltage to the second piezoelectric element.

In a mirror drive device, a first actuator section and a second actuator section are arranged on both sides of a mirror supporting section that supports a mirror section so as to sandwich the mirror supporting section. The upper electrode of a first actuator section includes a first electrode section and a second electrode section, and an upper electrode of a second actuator section includes a third electrode section and a fourth electrode section. The arrangements of the electrode sections correspond to stress distribution of principal stresses in the piezoelectric body in resonant mode vibration, and in a piezoelectric body portion that corresponds to positions of the first electrode section and the third electrode section and a piezoelectric body portion that corresponds to positions of the second electrode section and the fourth electrode section, stresses in opposite directions to each other are generated.
