An objective lens driving device includes an objective lens holder 2 that holds an objective lens 1, plural elastic supporting members 6A through 6F that support the objective lens holder 2, tracking coils 4A and 4B that drive the objective lens holder 2 in the tracking direction, tilting coils 11A and 11B that tilt the objective lens holder 2 with respect to the optical axis passing through the objective lens 1, a tracking control circuit 41 that drives the tracking coils 4A and 4B, and a tilting control circuit 11 that drives the tilting coils 11A and 11B. The tilting control circuit 11 drives the tilting coils 11A and 11B using a signal yielded by multiplying a tracking driving signal from the tracking control circuit 41 by a specific scaling factor K so as to cancel out a tilting force of the objective lens holder 2 generated by the tracking coils 4A and 4B.
