Abstract: An opto-electric composite transmission module includes a printed wiring board, an electrical connector provided on the printed wiring board, and an opto-electric hybrid board which is electrically connected to the printed wiring board via the electrical connector. The opto-electric hybrid board has a long shape. The opto-electric hybrid board includes an opto-electric conversion portion including a flexible wiring board, a metal support layer, and an optical waveguide film in order in a thickness direction, and an electrical connection portion disposed in one end portion in a longitudinal direction of the opto-electric hybrid board and including the flexible wiring board, and the metal support layer and/or the optical waveguide film. The electrical connection portion is inserted into the electrical connector.

Abstract: Provided is a photoelectric conversion module plug that includes a photoelectric hybrid board, a circuit board, an optical connector, and a plug case that houses them. At least a part of the photoelectric hybrid board faces the circuit board. The plug case has a thickness T2 in a facing direction between the photoelectric hybrid board and the circuit board. The ratio of the thickness T1 of the optical connector with respect to the thickness T2 of the plug case is 30% or more. The plug case has side walls having uneven region portions respectively and at least a part of the optical connector is located between the uneven region portions. An optical cable according to the present invention includes the module plugs and an optical cable that optically connects between these module plugs.
