An optical unit may include a movable body having an optical module, a fixed body, a support mechanism which turnably supports the movable body with respect to the fixed body with one or a plurality of directions intersecting an optical axis direction as a direction of a turning axis, and a flexible wiring board whose one end is connected with a connection part provided in the movable body and which is provided with a flat face region facing the optical axis direction. The flat face region is disposed on a side in a first intersecting direction intersecting the optical axis direction with respect to the movable body and is provided with a curved part curved without overlapping in the optical axis direction and is structured so that at least a part of the flat face region is overlapped with a position of the turning axis in the optical axis direction.
