Patent ID: 6996035

Claim:
An optical pickup device comprising an actuator for driving an objective lens to trace a signal track when a light beam is focused on a signal surface of a signal recording medium; an optical housing having mounted therein various optical parts arranged along an optical path to guide a light beam from a laser element to a signal surface of said signal recording medium and along another optical path to guide a reflected light beam from said signal surface to a photodetector, said optical pickup device being assembled by mounting said actuator in said optical housing, wherein a laser driving integrated circuit for driving said laser element is mounted in said housing, wherein a wiring pattern of an actuator line supplying drive signals to drive said actuator through a relay circuit board and a wiring pattern of a laser drive line supplying drive signals from said laser driving integrated circuit to said laser element are formed on the same flexible wiring board, wherein, when said flexible wiring board is folded, a shielding part connected to a ground line is arranged to intervene between overlapping wiring patterns of said actuator line and said laser drive line of the flexible wiring board.
