Light receptacle and light module

An optical receptacle which is disposed between a plurality of light emitting elements or a plurality of light receiving elements and a plurality of optical transmission members, and is configured to optically couple the light emitting elements or the light receiving elements to end surfaces of the optical transmission members, respectively, the optical receptacle comprising:

• an optical receptacle body including a plurality of first optical surfaces and a plurality of second optical surfaces, each of the first optical surfaces being configured such that light emitted from a corresponding one of the light emitting elements is incident on the first optical surface or being configured to emit light propagating inside the optical receptacle body toward a corresponding one of the light receiving elements, and each of the second optical surfaces being configured to emit the light incident on the first optical surface toward an end surface of a corresponding one of the optical transmission members or being configured such that light from a corresponding one of the optical transmission members is incident on the second optical surface;
• supporters which are connected to both ends of the optical receptacle body, respectively;
• 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,
• wherein the optical receptacle body and the 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, and
• the four adhesive reservoirs are disposed plane symmetrically with respect to the plane.
