An imaging device includes an imaging sensor having an imaging surface upon which an object image is formed via a photographing optical system; a guiding device for guiding the imaging sensor in a direction parallel to the imaging surface of the imaging sensor; and a driving device for driving the imaging sensor, while being guided by the guiding device, based on an output of an image-shake detector which detects a direction and magnitude of an amount of vibration applied to the photographing optical system. One and the other of the guiding device and the driving device are respectively provided in front of and behind an image-stabilizing plane, which is coincident with the imaging surface of the imaging sensor, with respect to an optical axis direction of the photographing optical system.
