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 coil that is disposed at a position facing the magnet in a housing that houses the assembly and displaces the assembly in the direction orthogonal to the optical axis in collaboration with the magnet; and a base that serves as a bottom of the housing, and 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.
