ABSTRACT:
An optical pickup has a laser mounting surface formed around an opening portion of a laser hole while a notch groove ranging from the laser mounting surface to an operating hole is formed in a laser hole side wall portion. A fitting piece removably fitted into the notch groove is provided integrally with a metal holder which is provided for supporting a photodiode and which is locked in the laser mounting surface. The operating hole is defined between a forward end of the fitting piece and an inner end of the notch groove. A laser diode is fitted into a lock hole of the holder coaxial with the laser hole while a radiator plate is attached to the outer surface of the holder. Thus, the laser diode is held between the holder and the radiator plate.
