Abstract
Provided are a lens driving device, a camera module, and a camera-mounted device for which the miniaturization and weight reduction can be achieved and the reliability can also be improved. The lens driving device includes AF and shake-correcting driving parts utilizing a voice coil motor. An AF fixing part includes an AF control part controlling the energization current through an AF coil part. The AF driving part includes upper and lower elastic supporting parts, auto-focusing power-source lines connected to power-supplying suspension wires functioning as a shake-correcting supporting part, signal lines connected to signal suspension wires functioning as a shake-correcting supporting part, and coil power-supply lines electrically connecting the AF control part to the AF coil part. The upper elastic supporting part functions at least as the AF power-supply lines or the signal lines, and the lower elastic supporting part functions as the coil power-supply lines.
