An optical receiver module capable of increasing the range in which the error in distance between a collecting lens and a light receiving section is allowed is provided. In the optical receiver module according to the invention, the optical receiver includes a semiconductor substrate to which the light from the collecting lens is input, and through which the light passes, and a light receiving section disposed on a side (a reverse side) of the semiconductor substrate, the side being further from the collecting lens, and adapted to receive the light transmitted through the semiconductor substrate, and then convert the light into an electrical signal. On a side (an obverse side) of the semiconductor substrate, the side being nearer to the collecting lens, there is formed a lens surface adapted to converge light from the collecting lens toward the light receiving section.
