記ベースを接着したことを特徴とする光検出器。 A thin plate-shaped photodetecting element consisting of a plurality of light-receiving areas is glued to one side of a plate-shaped base, and the other side of the base is fixed to the mounting surface of the base, and the light is reflected by the recording surface of the record carrier. A light beam is guided into the interior of the base, passes through a beam hole provided in the mounting surface, and is incident perpendicularly on the photodetecting element to convert the optical signal of the beam into an electrical signal, wherein the light beam is connected to the mounting surface. A photodetector characterized in that an auxiliary member is interposed between the auxiliary member and the base, one side of the auxiliary member is aligned with the mounting surface and fixed with a screw, and then the base is adhered to the other side of the auxiliary member. .
