A lens drive device is provided with a first fixed part, a first movable part, a first supporting part, and a Z-direction drive unit which moves the first movable section in an optical axis direction (the Z-direction) relative to the first fixed part and is constituted by an ultrasonic motor that converts vibration motion into rotational motion. The lens drive device further has a rotating body which rotates around the optical axis in response to rotational motion of the Z-direction drive unit, and a mechanical element which converts the rotational motion of the rotating body into linear motion in the optical axis direction, the first movable part being moved in the optical axis direction by rotation of the rotating body.

Lens driving apparatus, camera module and camera-mounted apparatus

A lens driving device includes: a movable part for accommodating a lens; and an ultrasonic motor having a resonance part configured to move the movable part by motion of the resonance part of the ultrasonic motor. The resonance part has a pair of arms, and is disposed such that only one of the arms is in contact with the movable part.
