Abstract: It is an object of the invention to provide a light-receiving module, in which alignments of optical axes of optical fibers and photodiodes can be easily carried out and efficiencies of light incidences on the photodiodes are not influenced by imperfections in a fabrication process. The light-receiving module according to the invention is composed of a photodiode-forming member and an optical fiber-supporting member. The photodiode-forming member is composed of light-receiving surfaces of the photodiode formed thereon and bank-shaped optical fiber-fixing guides for guiding the optical fibers along both their sides. The optical fiber-supporting member is composed of optical fiber-fixing grooves for fixing parts of the optical fibers near their output ends and reflector surfaces for changing directions of the lights emitted from light-emitting surfaces of the optical fibers.
