ABSTRACT:
In an optical pickup device, a flexible substrate (FPC) (2) and an auxiliary board (4) are fixed to an optical unit (5) with screws (11) before fixing an optical detector (1) to the FPC (2). After that, the optical detector (1) is pressed to the FPC (2) by probes (12), to bring lead portions (1a) into contact with conductor portions (2a). The optical detector1is singly moved by the probes (12) in that state, to perform position adjustment of the optical detector (1). Since the friction between the optical detector (1) alone and the FPC (2) is small, the position adjustment can be performed with high accuracy. Further, since the lead portions (1a) and the conductor portions (2a) are in contact with each other, it is possible to perform the position adjustment while observing an electrical signal outputted from the optical detector (1) through the FPC (2). Then, after determining the optimal position of the optical detector (1), the lead portions (1a) and the conductor portions (2a) are fixed to each other by soldering. Through such a manufacturing method, it is possible to improve the accuracy of position adjustment of the optical detector relative to the optical unit and improve the reliability of position of the optical detector after the position adjustment.
