An actuator includes a holder, a case, a support assembly, a first magnet, a second magnet, and a coil. The holder includes a sphere centered at a reference point and houses an optical module. The case houses the holder. The support assembly is in the case and supports the holder in a manner rotatable about the reference point. The first magnet is on a portion of the sphere in a first radial direction from the reference point. The second magnet is on a portion of the sphere in a second radial direction from the reference point. The coil is in the case and is energized to generate a magnetic field acting on the first magnet and the second magnet. The first magnet and the second magnet are located asymmetric to each other with respect to the reference point and have different lengths in a circumferential direction of the holder.
