An optical unit with shake correction function may have a movable member configured hold an optical element; a holder configured to support the movable member on an inner circumferential side via a swingable supporting mechanism; a first rotation supporting mechanism configured to rotatably support the holder at a periphery of an axis; and a fixing member configured to support the holder via the first rotation supporting mechanism. The fixing member may include a fixing member side opposing part that opposes to the holder in a Z axis direction (direction of the axis), and the holder may include a holder side opposing part that opposes to the fixing member side opposing part in the Z axis direction. The first rotation supporting mechanism may include a plurality of balls between the fixing member side opposing part and the holder side opposing par.
