PROBLEM TO BE SOLVED: To provide an objective lens driving device, in which the tilt correction of the objective lens is allowed although the structure is simple, also having small size and high thrust. SOLUTION: The objective lens driving device is furnished with a lens holder 2 for holding the objective lens 1 converging a light beam to irradiate a recording medium with the converged light, a focusing coil 3 and a tracking coil 4, and a base 10 for holding a plurality of driving magnets 6, and in this objective lens driving device, a tilt correcting coil 5 is arranged on the lens holder, and also the focusing coil 3, the tracking coil 4 and the tilt correcting coil 5 are arranged between a plurality of driving magnets 6. Also, by arranging two tilt correcting coils and controlling the direction and level of a current flowing into each of the tilt correcting coils 5-1, 5-2, the tilt direction and the tilt amount are adjusted.
