Optical unit

An optical unit comprising:

• a movable body comprising 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;
• a flexible circuit board whose one end is connected with a connection part provided in the movable body and which is disposed on a side in a first intersecting direction intersecting the optical axis direction with respect to the movable body;
• and
• a positioning part which is disposed on the side in the first intersecting direction with respect to the movable body and positions an other end of the flexible circuit board in the optical axis direction;
• wherein the flexible circuit board is folded so as to be overlapped with each other when viewed in the optical axis direction;
• and
• wherein a position in the optical axis direction of the turning axis is located within a range from the connection part to the positioning part.
