An objective lens driving device for an optical head has a lens holder including one or more tracking coils, one or more focusing coils, a plurality of wires which supply control currents to the tracking coils and the focusing coils and which support the lens holder in a cantilever manner, and a pair of movable magnets which are provided on a lower face of the lens holder in a track direction with an interval therebetween. A base part includes a pair of fixed magnets which are arranged so as to be opposed to the tracking coils and the focusing coils of the lens holder thereby to act thereon, a pair of right and left coils for correcting tilt angles which are arranged so as to be respectively opposed to the movable magnets thereby to act thereon, and power supply lines for supplying control currents to the tilt angle correcting coils.
