Abstract: An optical receptacle includes: an optical receptacle body; two supporters which are connected to a respective end of the optical receptacle body, wherein each supporter is connected to one end of the optical receptacle body at a central portion of the respective supporter, and the two supporters face each other with a space therebetween; and four adhesive reservoirs which are disposed at respective four corners of the optical receptacle in plan view, wherein each of the adhesive reservoirs is a through hole or a recess, and the through hole or the recess is surrounded circumferentially by the supporter. The optical receptacle body and the two supporters together have a plane symmetrical shape with respect to a plane parallel to an optical axis of the light emitted from each of the second optical surfaces. The four adhesive reservoirs are disposed plane symmetrically with respect to the plane.

Abstract: The light receptacle has: a light transmitting light receptacle main body (130); support parts (140) disposed on both ends of the light receptacle main body (130); first optical surfaces (132) to which light emitted by light-emitting elements (114) is made incident; second optical surfaces (136) that output light made incident at the plurality of first optical surfaces (132) toward the end surfaces of a plurality of light transmitting bodies (116); and four adhesive holding parts (142) that are through holes or recesses with the entire periphery thereof surrounded by the support parts and that are disposed at the four corners of the light receptacle (120) in a plane view. The light receptacle main body (130) and the support parts (140) have a plane-symmetrical shape, and the four adhesive holding parts (142) are disposed in plane-symmetrical positions.
