Disclosed in the present invention is a photosensitive chip drive device, comprising a movable carrier, a fixing base, a driving mechanism, a guide slot, a supporting mechanism, and a magnetic attraction member, wherein the movable carrier is used to carry a photosensitive component; the fixing base and the movable carrier are arranged opposite each other and at an interval in an optical axis direction; the driving mechanism comprises at least one group of coils and at least one group of magnets, the magnets being mounted on a peripheral side of the fixing base, and at least one of the groups of coils being mounted on a peripheral side of the movable carrier; the guide slot is provided between the movable carrier and the fixing base; the supporting mechanism is movably arranged in the guide slot; and the magnetic attraction member is mounted to the movable carrier and arranged opposite the magnets, so that a magnetic attraction force is generated, in the optical axis direction, between the magnetic attraction member and the magnets, such that the supporting mechanism is clamped between the fixing base and the movable carrier. Thus, the photosensitive chip drive device has a simple structure, and realizes the image stabilization correction and reset functions of the photosensitive component in an orthogonal plane of an optical axis while ensuring the miniaturization of the camera module.
