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 comprises: an assembly that is formed by assembling the lens holder together with a conductive body and comprises a circuit that receives supplied power; a base that is disposed at a position spaced from the assembly and has an aperture through which the optical axis passes; and a plurality of suspension wires that are disposed around the aperture and support the assembly such that the assembly is displaceable in the direction orthogonal to the optical axis, wherein the plurality of suspension wires include a first suspension wire configured to supply power to the circuit, and a second suspension wire configured to supply power to the circuit via a path different from that of the first suspension wire.
