Abstract

A lens drive device capable of positioning a lens at a desired position and in turn improving a focus adjustment function. The lens drive device has a movable lens body (3), a stationary body (2) for supporting the movable lens body (3) so that it can move in a lens axis direction, a drive mechanism (5) for moving the movable lens body (3) in the lens axis direction, and sheet springs (131, 132) for limiting, when a current is supplied to coils (141, 142) to produce electromagnetic force, the movement of the movable lens body (3) caused by the electromagnetic force.
