Abstract
The purpose of the present invention is to provide an optical unit with a shake correction function such that even when a photo reflector is provided by using a gap between a side surface of a movable body and a side surface of a fixed body, an appropriate relationship between an output from the photo reflector and the rock angle of the movable body can be obtained. In an optical unit () with a shake correction function, a movable body () is rocked about a rock fulcrum () by a driving mechanism () for shake correction, and thereby shaking is corrected. At that point, the movement of the movable body () is monitored by providing a first photo reflector () and a second photo reflector () on side surfaces of a fixed body (). Here, a smooth layer () such as a resin tape, a metal sheet, a coating layer, plate glass or a reflective board is laminated onto side surfaces of the movable body () at a region facing the first photo reflector () and a region facing the second photo reflector ().
