Abstract
A lens driving device, a camera module, and a camera-mounted device are provided, which are capable of reducing the effect of external magnetism and of being reduced in size and profile thereof. The lens driving device includes an AF driving part configured to move, with respect to an AF fixing part, an AF movable part in a Z-direction extending along an optical axis, and an OIS driving part configured to move, with respect to an OIS fixing part, an OIS movable part in an X-direction and a Y direction each orthogonal to optical axis. The OIS driving part and the AF driving part are each composed of an ultrasonic motor. In a rectangle defined by two sides where the OIS driving part is disposed, the AF driving part is disposed along a side different from the two sides.
