Patent attributes
A lens driving apparatus includes a housing; a lens holding member positioned in the housing for holding a lens body, a coil, a detection magnet, and a balance magnet; first and second magnetic field generating members facing each other across the coil and the lens holding member; the detection magnet for detecting a position of the lens holding member; a magnetic detection member facing the detection magnet; the balance magnet facing the detection magnet across an optical axis of the lens body; and first and second leaf springs conducted to the ends of the coil, movably supporting the lens holding member in the optical axis direction. The detection magnet is disposed closer to the first magnetic field generating member than to the second magnetic field generating member, and the balance magnet is disposed closer to the second magnetic field generating member than to the first magnetic field generating member.
