PROBLEM TO BE SOLVED: To provide a light receiving module capable of being easily manufactured and having low cost, in a light receiving module for separating and receiving light having a plurality of wavelengths. SOLUTION: A light receiving module is constituted of a base plate on which an optical fiber 10 and a light receiving element 20 are so installed that one end surface of the optical fiber 10 and the light receiving surface of the light receiving element 20 may be faced to each other; an optical filter formed on one end surface of the optical fiber 10, for transmitting light of the first wavelength, and for reflecting light of the second wavelength; and a wavelength selecting material interposed between the optical filter and the light receiving surface, for transmitting light of the first wavelength, and not for transmitting light of the second wavelength.
