PROBLEM TO BE SOLVED: To provide a lens drive device capable of performing accurate image blur correction.SOLUTION: The lens drive device comprises: a base member 2; a movable member 10 provided on the base member 2 and moving in a plane perpendicular to an optical axis C; first drive means 11 for moving the movable member 10 in a direction perpendicular to the optical axis C in accordance with image blur; a lens frame 16 attached to the movable member 10 and moving in the direction of the optical axis C; and second drive means 19 for moving the lens frame 16 in the direction of the optical axis C. The second drive means 19 has a first magnet 22a fixed to the movable member 10 and a first coil 22b fixed to the lens frame 16. The lens drive device further includes a Hall element 27 arranged so as to face the first magnet 22a in the direction of the optical axis C, and detecting the change in the magnetic field of the first magnet 22a. |
