Abstract
In an object lens actuator, stiffness of a lens holder is improved and the higher order resonance frequency is sufficiently increased. The stiffness of the lens holder is improved by providing a flat plate perpendicular to the focusing direction between the side wall of a lens holding part and the outer sidewall along the tracking direction at approximately the middle of both ends of the lens holder along the focusing direction.
