Abstract
A lens drive apparatus that displaces a lens holder in a direction of an optical axis and a direction orthogonal to the optical axis in collaboration with a magnet and a coil that includes: a first coil that is disposed at a position shifted in a radial direction of the lens holder with respect to the magnet and displaces the lens holder in the direction of the optical axis; and a second coil that is disposed at a position shifted in the direction of the optical axis with respect to the magnet and displaces the lens holder in the direction orthogonal to the optical axis, comprises a Hall device that is disposed at a position shifted in the direction of the optical axis with respect to the second coil and detects a position of the magnet in the direction orthogonal to the optical axis.
