Abstract
An optical unit with shake correcting function may include a movable module on which an optical element is mounted, a fixed body which supports the movable module, a shake detection sensor which detects a shake of the movable module, a shake correction magnetic drive mechanism which swings the movable module on the fixed body on a basis of a detection result of the shake detection sensor to correct the shake of the movable module, and a spring member which is connected with the fixed body and the movable module. A stopper mechanism may be structured between the movable module and the fixed body, and the stopper mechanism may moving ranges of the movable module due to the shake.
