Thus, by providing a plurality of optical receptacle main bodies in one support member, optical communication becomes possible by each optical receptacle main body, and a communication speed equivalent to the case where a plurality of optical modules are provided can be realized. Furthermore, although there are a plurality of optical receptacle bodies, there is only one support member, and one support member covers the elements (photoelectric conversion elements, drive ICs) of the plurality of optical modules corresponding to the plurality of optical receptacle bodies. It is also possible to reduce the space required between the optical modules and save space. The plurality of optical receptacle bodies may be arranged in parallel so that the second optical surface facing the light transmission body is in the same plane on the mounting surface of the support member, or the second optical surface is not in the same plane It may be located at

The optical receptacle main body has a first optical surface facing the photoelectric conversion element and a second optical surface facing the light transmission body, and the light from the photoelectric conversion element incident on the first optical surface is the second optical surface The light from the light transmission body, which has been transmitted to the second optical surface, is transmitted to the photoelectric conversion element, which is opposed to the first optical surface. The optical receptacle main body has a main body side mounting structure, and the main body side mounting structure is mounted on any of a plurality of supporting member side mounting structures formed on the mounting surface of the supporting member, and is bonded with an adhesive. It is fixed to the member. The main body side mounting structure is preferably formed on a surface other than the first optical surface and the second optical surface, and the optical receptacle in the supporting member is engaged or engaged with the supporting member side mounting structure.

The support member is preferably configured as a cover for protecting the photoelectric conversion element mounted on the substrate and the drive IC, and surrounding the portion other than the portion where the light transmission body is disposed with the support member. On the mounting surface of the support member, the support member side attachment structure is more in number than the number of body side attachment structures of at least the plurality of optical receptacle bodies, preferably the number of body side attachment structures of the plurality of optical receptacle bodies It is formed. When the support member side attachment structure is formed in a number greater than the number of main body side attachment structures of the plurality of optical receptacle bodies, each optical receptacle body is located at the position of each support member side attachment structure on the attachment surface of the support member.
