To successfully reduce a coupling loss in optical power on the reception side that occurs due to an axial deviation on the transmission side. A connector body is included that includes a lens performing formation with respect to light that exits a light emitter, and causing light obtained by the formation to exit the lens. The lens includes a circular first lens portion situated in a center portion of the lens, and a ring-shaped second lens portion situated around an outer circumference of the first lens portion. The second lens portion changes a light path of a portion of input light when the portion of the input light is input to the second lens portion, such that the light path of the portion of the input light is oriented toward a direction of an optical axis of the lens, the input light being input light of which an optical axis deviates from the optical axis of the lens.
