An optical pickup device comprises a lens holder to hold an objective lens for irradiating a laser beam onto an optical disc; outer and inner circumferential side wires fixed at one ends thereof to outer and inner circumferential sides of the lens holder and extending substantially in parallel to the optical disc; a suspension holder for suspending and supporting the other ends of the outer and inner wires to cantilever the lens holder; and a magnetic drive circuit for driving the lens holder in a focusing direction and a tracking direction. The outer wires have an effective length longer than that of the inner wires. This makes it possible to tilt the objective lens so as to compensate the tilt of the optical disc, if any, at the time of recording and reproduction, thereby reducing jitter and improving recording and reproduction performance of the optical pickup device with simple structure.
