Abstract
The lens driving device according to the present invention is provided with: an autofocus drive part for moving an autofocus movable part with respect to an autofocus fixed part in an optical axis direction and thereby automatically performing focusing; a shake correction drive part for correcting shake by causing a shake correction movable part to oscillate with respect to a shake correction fixed part in a plane orthogonal to the optical axis direction; and a sub-stopper part for restricting the distance that the autofocus movable part can move toward the image side in the optical axis direction to within an allowable range of displacement of a lens part, the sub-stopper part being interposed between the autofocus movable part and the shake correction fixed part.
