In a photodetector module including a photodetector element and an optical coupling member comprising a ferrule and an optical fiber inserted into the ferrule at a center thereof, a first transparent resin member integrates the photodetector element and the one end of the optical fiber so that the photodetector element and the one end of the optical fiber are embedded therein. A second resin member integrates the optical coupling member and the first transparent resin member so that a part of the optical coupling member and the first transparent resin member are embedded therein. Alternatively, the optical coupling member may comprise a lens member and a lens holder for holding the lens member. In this event, a transparent resin member integrates the photodetector element and the optical coupling member so that the photodetector element and a part of the optical coupling member are embedded therein.
A photodetector module including a photodetector element and an optical coupling member comprising a ferrule and an optical fiber inserted into said ferrule at a center thereof, said optical fiber having one end opposite said photodetector element and being separated from said photodetector element by a predetermined gap and having another end which has an end surface abraded together with an end surface of said ferrule, said photodetector module further comprising:
