ABSTRACT:
The reflective collection-type light receiving unit of the present invention is a reflective collection-type light receiving unit having a light receiving element which receives spatial light on which an information signal is superimposed after being reflected and collected via a concave mirror. The light receiving element is arranged approximately at the center inside the concave mirror, with the light receiving plane thereof facing to the reflection plane of the concave mirror. A pair of electrode leads connected to both electrodes of the light receiving element are extended so as to be opened from the center on the front plane of the concave mirror to both sides and connected to a light receiving circuit by way of the lateral plane of the concave mirror.
