Abstract
The present invention provides a camera module and a camera-mounted device that can accurately detect the position of a movable body in a blade drive device and improve reliability. [Solution] The camera module comprises an optical element drive device and a blade drive device. The optical element drive device comprises a first drive unit consisting of a first coil and a plurality of first magnets. The blade drive device comprises a second movable part and a blade detection sensor that magnetically detects the rotational movement of the second movable part. The blade detection sensor is located in a first region between adjacent first magnets in a plan view as seen from the optical axis direction.
