Abstract
An optical unit may include a fixed body; a movable module which holds an optical element; and a shake correction drive mechanism which is structured to generate a drive force for swinging the movable module with respect to the fixed body. The shake correction drive mechanism may include a plurality of permanent magnets which are provided on an outer peripheral face of the movable module at positions separated in a circumferential direction around an optical axis of the optical element; and a sheet-shaped coil which is extended in a circumferential direction in the fixed body and is integrally provided with a plurality of coil parts facing the permanent magnets and a terminal part electrically connected with the coil parts.
