A light-receiving-element module is provided which has a greater high-frequency characteristic and light receiving sensitivity than those of conventional technologies. A light-receiving-element module includes a first refractive part that refracts an optical signal with a first wavelength or an optical signal with a second wavelength, and a second refractive part that refracts the optical signal with the first wavelength and the optical signal with the second wavelength refracted by the first refractive part so as to reduce a chromatic aberration. The light-receiving-element module also includes a light receiving element that converts the optical signal with the first wavelength or the optical signal with the second wavelength refracted by the second refractive part into an electric signal by photoelectric conversion.
