Abstract
A lens driving device includes a base, a lens holder capable of holding a lens body, a movable support, a leaf spring that is disposed on the movable support and supports the lens holder such that the lens holder is movable along an optical axis of the lens body, a suspension wire that rises from the base along the optical axis and supports the movable support such that the movable support is movable in a direction intersecting the optical axis, and a drive mechanism that moves the movable support in the direction intersecting the optical axis. The leaf spring includes a spring body fixed to the movable support, a wire fixing part to which the suspension wire is fixed, and a first beam and a second beam that are disposed between the spring body and the wire fixing part and torsionally deformable.
