An autofocus actuator is provided by which it is possible to easily confirm that a holder and a yoke do not make contact with each other even when the space between the holder and the yoke is made as small as possible in order to improve shock resistance. The autofocus actuator includes light transmission holes for confirming a space between an inner peripheral surface of an inner cylindrical portion of the yoke and an outer peripheral surface of a cylindrical portion of the holder provided with a lens unit and being capable of adjusting its position in the optical axis direction by supplying electrical power to a coil secured to the holder. The light transmission holes are provided at predetermined positions of a flange portion of the holder and a stopper for attaching a leaf spring to the holder, respectively, so that light can pass therethrough.
