PROBLEM TO BE SOLVED: To provide a lens driving device capable of easily performing adjustment of a magnetic suction force working between a magnet and a magnetic body.SOLUTION: A lens driving device is a device which holds a lens and a lens holding frame movably supported in a plane orthogonal to an optical axis in a frame body. The lens driving device includes: a driving part for moving the lens holding frame in a plane orthogonal to an optical axis in collaboration with a coil 6d and a magnet 6b; and a plate-like return yoke 11 facing the magnet 6b in the optical axis by sandwiching the coil 6d therebetween. The return yoke 11 has hollow parts 61, 62 concavely formed toward a center of gravity X1, and the return yoke has a line-symmetric shape for a straight line S passing through the center of gravity X1 of the return yoke in a plane orthogonal to the optical axis, and the hollow parts 61, 62 are provided at two facing locations. |
