摘要： A lens actuator includes a carrier that is configured to retain a lens; a first AF coil that is disposed in the carrier while wound about an axis perpendicular to a lens retaining surface; first to fourth magnets that are disposed opposite the first AF coil in four directions parallel to the lens retaining surface; a first OIS coil that is disposed opposite the first magnet; and a second OIS coil that is disposed opposite the second magnet. A current is passed through the first AF coil to move the carrier in a vertical direction along an axis. The currents are passed through the first and second OIS coils to a movable unit in front-back and left-right directions. Therefore, weight reduction of the movable unit can be achieved to provide a lens actuator, in which electric power saving can be achieved.
