Abstract: An actuator of the type employing a two-degree-of-freedom vibration system includes a first mass portion, a second mass portion, a pair of supporting portions, as least a pair of first elastic connecting portions which connects the first mass portion to the supporting portion so that the first mass portion can rotate with respect to the supporting portion, and at least a pair of second elastic connecting portions which connects the second mass portion to the first mass portion so that the second mass portion can rotate with respect to the first mass portion. The first mass portion is driven by the application of an alternating voltage, causing the second mass portion to rotate, and the frequency of the alternating voltage is set so as to be substantially the same as a lower resonance frequency of resonance frequencies of the two-degree-of-freedom vibration system at which the first mass portion and the second mass portion resonate. This makes it possible to provide the actuator capable of operating at high speed and at low voltage and achieving a large rotation angle.
