Abstract: There is provided an image-shake correcting device having a correcting optical unit, which is capable of performing image shake correction with high accuracy using a simple construction and without reducing the degree of freedom of layout and without the need to increase the size of the device. At least one magnet member is provided in the correcting optical unit. At least one coil member is arranged away from the magnet member in a direction of the optical axis of the optical unit. A first magnetic member is arranged away from the magnet member in the direction of the optical axis. A second magnetic member is arranged away from the magnet member in the direction of the optical axis and at a side of the magnetic member remote from the first magnetic member. Energization of the coil member causes the correcting optical unit to be driven in a direction intersecting with the optical axis to correct image shakes.
