PROBLEM TO BE SOLVED: To reduce the front projected area of a camera shake correcting mechanism and to miniaturize an optical device by positioning the air-core part of an air-core coil for driving a correction lens on the optical path of the correction lens. SOLUTION: A camera shake correction unit 10 is provided with a correction lens frame 11 installed to position the correction lens 12 on an optical axis. The y-driving air-core coil 20 for driving the lens 12 in a direction (y) is stuck to the front surface of the front side flange of the frame 11. The coil 20 is a flat air-core coil where a conductor is wound in a frame-state along the outer peripheral shape of the front surface of the front side flange. The lens 12 is arranged to be positioned inside the air-core part 20a. The x-driving air- core coil 24 is stuck to the back surface of the moving supporting frame of the frame 11. In a state that the coils 20 and 24 are not energized, the centers of the air-cores of the air-core parts 20a and 24a are aligned with the optical axis 0 passing through the lens 12. |
