An optical unit with a shake correction function may include a movable module holding an optical element; a fixed body; a support mechanism swingably supporting the movable module at a midway position in an optical axis direction; and a shake correction drive mechanism to swing the movable module. The movable module may include an optical module which holds the optical element; and a weight provided on one side of a front side and a rear side in the optical axis direction of the optical module, the weight being configured to shift a gravity center position of the movable module to a support position side of the support mechanism relative to a gravity center position of the optical module in the optical axis direction. An end face of one side of the weight may be formed in a flat face which is perpendicular to the optical axis direction.
