1. An optical unit, comprising:
a movable body provided with an optical module;
a fixed body;
a support mechanism that supports the movable body in a rotatable manner with respect to the fixed body with a single or a plurality of directions intersecting an optical axis direction of the optical module as a direction of a rotation axis;
a flexible printed circuit board that has a first end connected to a connection part provided on the movable body, the flexible printed circuit board being disposed on a side in a first intersecting direction intersecting the optical axis direction with respect to the movable body; and
a positioning part that is disposed on the side in the first intersecting direction with respect to the movable body and that positions the flexible printed circuit board,
wherein
the flexible printed circuit board has a bent part formed by bending the flexible printed circuit board at least twice between the connection part and the positioning part along an extension direction,
the bent part includes
a first bent portion between the connection part and the positioning part along the extension direction, and
a second bent portion between the first bent portion and the positioning part along the extension direction,
the first bent portion of the flexible printed circuit board is located on a side where the connection part is located with respect to a reference plane that extends from a rotation center of the rotation axis of the movable body along the first intersecting direction,
the second bent portion of the flexible printed circuit board is located on the reference plane or on a side different from the side where the connection part is located with respect to the reference plane,
the fixed body includes a wall that covers a front surface of the flexible printed circuit board,
the wall is positioned on the side in the first intersecting direction with respect to the movable body,
the fixed body further includes a frame part surrounding the movable body, and
the wall of the fixed body extends from the frame part in the first intersecting direction away from the movable body.
