Abstract
An actuator including a detection target disposed on a surface of a lens barrel, and a position detecting unit including two or more sensing coils and configured to detect a displacement of the detection target in a first direction perpendicular to an optical axis, wherein when the detection target moves in a second direction perpendicular to the optical axis, an area of overlap between each of the two or more sensing coils and the detection target is maintained constant.
