1. A light-receiving module comprising:
a light-receiving device;
a receptacle including an optical fiber stub;
a lens including an incident-side curved surface, an emission-side curved surface, and a cylindrical portion provided between the incident-side curved surface and the emission-side curved surface; and
a receptacle holder holding the receptacle so that the lens and the optical fiber stub are not in contact but separated from each other,
wherein when a single beam of light out from the optical fiber stub enters the lens through the incident-side curved surface, the single beam of light is condensed inside the lens and then spreads again, and the single beam of light out from the emission-side curved surface is condensed onto a light-receiving surface of the light-receiving device.
