PROBLEM TO BE SOLVED: To correct the tilt of a lens to an optical axis when performing focusing operation in a lens driving device where driving mechanisms are arranged asymmetrically with the center of the lens. SOLUTION: The lens driving device is provided with: a movable part 3 capable of moving in the optical axis direction of the lens 4 while holding the lens 4; a fixed part 2 in which the movable part 3 is housed; the driving mechanisms 6, 7 and 8 arranged asymmetrically with the center of the lens 4 and moving the movable part 3 in the optical axis direction; and an elastic member 9 whose one end and the other end are respectively connected to the movable part 3 and the fixed part 2. Then, it is provided with a locking member 10 near the driving mechanisms 6, 7 and 8 of the movable part 3. When the movable part 3 moves upward along the optical axis from an initial position, the locking member 10 abuts on a top surface component 30 on the upper side of the lens driving device 1, so that the movable part 3 is moved with an abutting part 15 between the locking member 10 and the top surface component 30 as a fulcrum.
