Abstract: A lens driving device includes a fixed member including a base member; a lens holder including a cylindrical portion configured to hold a lens body; and a plurality of shape memory alloy wires configured to move the lens holder with respect to the fixed member. The fixed member includes a fixed contact that forms a stopper configured to restrict movement of the lens holder. The lens holder includes an elastic portion formed of a material that is softer than that of a synthetic resin material forming the cylindrical portion of the lens holder. The elastic portion includes a movable contact that faces the fixed contact of the stopper so as to be able to contact the fixed contact of the stopper.
