PROBLEM TO BE SOLVED: To provide an image stabilizer in which a camera shake in the movement direction of an optical axis of a photographing lens of a camera as well as image blur due to a camera shake about an axis parallel with the optical axis of the photographing lens of the camera can be corrected without causing upsizing. SOLUTION: A control means drives and controls a Y-direction driving coil (CYA) corresponding to one Y-direction displacement detection means (SYA) based on a differential signal between: a sum signal of an output signal of Y-direction vibration detection means (GSY) and an output signal of a rotation detection means (GSR); and an output signal of the one Y-direction displacement detection means (SYA) out of two Y-direction displacement detection means (SYA and SYB). The control means drives further drives and controls a Y-direction driving coil (CYB) corresponding to the other Y-direction displacement detection means (SYB) based on a differential signal between: the difference signal of the output signal of the Y-direction vibration detection means (GSY) and the output signal of the rotation detection means (GSR); and an output signal of the other Y-direction displacement detection means (SYB) out of the two Y-direction displacement detection means (SYA and SYB).
