ABSTRACT:
This invention aims at reducing a rolling moment generated in coils mounted to lens holder side face without losing drive forces in a focusing direction and tracking direction in an objective lens drive of an optical pickup device. By shifting a coil line portion near the objective lens of two coil line portions substantially parallel to the tracking direction of the first coil in a direction departing from a lens optical axis, increase and decrease in drive forces generated in right and left first coils when the lens holder is moved in the tracking direction cancel each other so as to eliminate imbalance between the right and left drive forces.
