The coupling loss of optical power on a reception side due to an axis deviation on a transmission side is satisfactorily mitigated. A connector body including an optical path adjusting unit and a lens is provided. The optical path adjusting unit adjusts an optical path such that the diameter of incident light is reduced while the incident angle is kept. The lens collects light whose optical path has been adjusted, and causes the light to be incident on a light receiver. For example, light incident on the optical path adjusting unit is collimated light. Furthermore, for example, the optical path adjusting unit has a through hole in a central portion. While the incident angle of light to the light receiver satisfies an NA, the focal distance of the lens is decreased. This can mitigate the coupling loss of optical power on a reception side due to an axis deviation on a transmission side.
