Optical receptacle, optical module, and method for manufacturing optical module

An optical receptacle configured to be disposed between an optical transmission member and a photoelectric conversion device including a photoelectric conversion element disposed on a substrate, the optical receptacle being configured to optically couple the photoelectric conversion element and an end surface of the optical transmission member, the optical receptacle comprising:

• an optical receptacle main body;
• a supporting member configured to support the optical receptacle main body;
• and
• an adhesive agent configured to bond the optical receptacle main body and the supporting member,
• wherein the optical receptacle main body includes:
• a first optical surface configured to allow incidence of transmission light emitted from the photoelectric conversion element, or to emit, toward the photoelectric conversion element, reception light having passed through inside of the optical receptacle main body after being emitted from the end surface of the optical transmission member,
• a second optical surface configured to emit, toward the optical transmission member, the transmission light having passed through the inside of the optical receptacle main body after being emitted from the photoelectric conversion element, or to allow incidence of the reception light emitted from the optical transmission member,
• a reflection surface configured to reflect, toward the second optical surface, the transmission light incident on the first optical surface, or to reflect, toward the first optical surface, the reception light incident on the second optical surface,
• a first fitting part disposed in a surface opposite to a surface where the first optical surface is disposed, and
• a recess formed on a side of the surface where the first fitting part is disposed,
• wherein the supporting member includes:
• a supporting member main body including an installation surface for installation to the substrate,
• a second fitting part disposed in an inner surface of the supporting member main body, the inner surface facing the surface where the first fitting part of the optical receptacle main body is disposed, the second fitting part being fitted with the first fitting part, and
• a through hole facing the recess of the optical receptacle main body and opening at the inner surface and an outer surface of the supporting member main body, the outer surface being opposite to the inner surface,
• wherein the adhesive agent is disposed in the recess of the optical receptacle main body such that the adhesive agent makes contact with an inner surface of the recess and the inner surface of the supporting member main body, and
• wherein the optical receptacle main body is located on a side of the supporting member with respect to the installation surface.
