The optical unit 10 includes a light source 12, an electromagnetic wave generator, a first reflector 14 configured to reflect emitted light L emitted from the light source 12 and electromagnetic waves emitted by the electromagnetic wave generator in a first reflection region R1 whose reflection direction is changed periodically, and a second reflector 16 configured to reflect first reflected light L1 reflected by the first reflector and first electromagnetic waves again in a second reflection region R2 whose reflection direction is changed periodically. The first reflector 14 is configured to scan the second reflection region R2 with the first reflected light L and the first electromagnetic waves. The second reflector 16 is configured to form a light distribution pattern by performing scanning with second reflected light L2, and to detect a surrounding object by performing scanning with second electromagnetic waves.
