Abstract
Provided is an actuator capable of efficiently detecting the vibration of a driven part which is a movable body (an imaging module, for example), over a wide range even with a narrow mounting space. A fixed body in this actuator comprises: a gyroscope for detecting the vibration of the fixed body; a first Hall element for detecting a first position of a lens part associated with a movement in a first direction orthogonal to the optical axis of the lens part; and a second Hall element for detecting a second position associated with a movement in a second direction orthogonal to the first direction. The vibration of the driven part is corrected on the basis of the vibration of the fixed body detected by the gyroscope and the positions detected by the first and second Hall elements.
