Lens driving device, camera module and camera mounting device

The invention relates to a lens driving device, a camera module and a camera-mounted device. In the lens driving device of the present invention, shake correction is performed by moving a first movable part in an optical axis orthogonal plane, the lens driving device has a rectangular shape extending in an X direction and a Y direction which are orthogonal to each other in the optical axis orthogonal plane, and is provided with an intermediate direction movement restricting part. And an intermediate direction movement restricting section that is provided at a position corresponding to the four corners of the rectangular shape and restricts the movement of the first movable section in an intermediate direction, which is a direction that forms an angle of 45 degrees with the X direction and the Y direction. Each of the intermediate-direction movement restricting portions has a fixed-side restricting portion provided to the first fixed portion and a movable-side restricting portion provided to the first movable
