PROBLEM TO BE SOLVED: To provide an objective lens driving device which has a satisfactory vibration characteristic and which is capable of miniaturizing and thinning an optical system. SOLUTION: This objective lens driving device is provided with an objective lens 1 converging a light beam, driving coils 3,4 for driving the objective lens 1 in the direction of its optical axis or in a direction orthogonal to the optical axis, a lens holder 2 holding the lens 1 and an elastically holding member 8 elastically supporting the movable part constituted at least of the lens 1 and the holder 2. In this case, a second lens 13 except the lens 1 is additionally installed in the movable part. |
