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 comprises: an assembly that is formed by assembling the lens holder together with a magnet disposed around the lens holder; a housing that has a base and a cover that are configured to house the assembly; and a planar coil that is attached inside of the housing such that a coil plane thereof facing the magnet is in parallel with the optical axis, the planar coil being configured to displace the assembly in the direction orthogonal to the optical axis in collaboration with the magnet, wherein the base has an aperture having a size greater than a displacement range of the optical axis resulting from displacement of the assembly in the direction orthogonal to the optical axis.
