A lens driving device which is small in size and good in focus adjustment and hand-shake correction disclosed, including: a housing, including a fixing base having a circuit substrate and a cover forming a receiving space; a spring piece connecting a lens module and a supporting frame; a supporting component for supporting the supporting frame and a second supporting frame in the housing; a first magnet steel, mounted and fixed on the supporting frame; a first drive coil, mounted on the lens module to enable a movement in an optical axis direction under an electromagnetic action; and a second drive coil, disposed on the fixing bases, and oppositely disposed near a horizontal plane of a gravity center of the lens module above a second magnet steel so that the second magnet steel mounted on the supporting frame moves along a direction orthogonal to the optical axis under the electromagnetic action.

A lens barrel having one end and the other end includes: a first frame that is movable and holds optical members; a second frame that is arranged to be relatively movable toward the other end with respect to the first frame, and holds optical members; and a third frame that is mounted on the first frame so as to be movable, and holds an optical member. The first frame includes a first stopper portion that comes into contact with the third frame to limit movement toward the one end. The first frame includes a second stopper portion that comes into contact with, when the first frame is most distant from the second frame, the third frame to limit movement toward the other end. The second frame includes a third stopper portion that has a contact surface located close to the one end with respect to the second stopper portion, and that comes into contact with, when the second frame is located within a range on the optical axis where the third frame is movable, the third frame to limit movement toward the other end.
