In order to improve reliability of an optical disk drive apparatus at low cost, a flexible substrate for making connection between an optical pick-up device incorporated in the optical disk drive apparatus and a drive side is divided into a first flexible substrate fixed to the optical pick-up body (for example, upper surface), and a second flexible substrate connected to the first flexible substrate and extending to the drive, wiring conductors formed on a connection end portion of the first flexible substrate and wiring conductors formed on a connection end portion of the second flexible substrate are superposed at a region adjacent an end of the case of the optical pick-up device body, and connected to each other by joining material, and a connection section between the wiring conductors is held down by a cover for protecting the optical pick-up device body.
