Abstract
An optical receptacle includes a light dividing surface that divides light from a light-emitting element into monitor light and coupling light to be coupled with an optical transmission body using total reflection. The light dividing surface includes a first curved surface that protrudes to the side opposite to a first surface from a first virtual reference surface having a slope angle of angle α[°] in relation to the first surface on a photoelectric conversion device side of an optical receptacle main body and a second curved surface that is connected to the first curved surface and protrudes to the side opposite to the first surface from a second virtual reference surface having a slope angle of angle β[°] in relation to the first surface, in which α and β satisfy α>β>critical angle.
