Abstract
This optical receptacle comprises: a first optical surface through which light from a photoelectric conversion element is incident; a second optical surface through which the incident light is emitted to the optical transmitter side; an optical separation part which separates the incident light into monitor light that goes to a detection element and signal light that goes to the optical transmitter; and a third optical surface through which the monitor light is emitted to the detection element side. The securing part secures the optical transmitter such that the signal light from the second optical surface arrives at the end surface of the optical transmitter at a position farther than the focus of the second optical surface. The light flux diameter in the light separation part of the light incident through the second optical surface is smaller than the light flux diameter of the light in the second optical surface.
