PROBLEM TO BE SOLVED: To dispense with alignment or correction of optical axes by eliminating optical axis adjustment between a light emitting element 2 and an optical transmission line 1 and providing a state of permanently aligned optical axes from the original manufacture to the subsequent use of the module. SOLUTION: The photoelectric coupling/transmitting module is equipped with the optical transmission line 1 for guiding and transmitting light and with the light emitting element 2 installed at the end of this transmission line 1. The light emitting element 2 has an electron emitter 6 for releasing electrons, a gate electrode 8 for accelerating the electrons released form this emitter 6, a light emitting body 9 installed at the end face of the line 1 and for receiving the electrons and emitting light, and an anode 10 for guiding the electrons to the light emitting body 9.
