PROBLEM TO BE SOLVED: To provide an optical transmission module with which it is possible to align optical cables with high accuracy, and a method for manufacturing the optical transmission module.SOLUTION: An optical transmission module 100 comprises: a surface emission laser 10 having a light-emitting unit 11 for outputting an optical signal; a circuit board 20 provided with a through-hole 21 for letting the optical signal outputted by the light-emitting unit 11 pass through; an optical cable 30 for propagating the optical signal outputted from the light-emitting unit 11, and having a metal film 31 formed on at least part of the outer circumferential face; and a guide holding member 40 having a through-hole 41 for inserting the optical cable 30 therethrough, and at least one of the faces parallel to the optical axis of the optical cable 30 is optically polished. The surface emission laser 10 is flip-chip mounted on the circuit board 20 so that the light-emitting unit 11 is located above the through-hole 21, and the guide holding member 40 for holding the optical cable 30 is mounted so as to face the surface emission laser 10 via the circuit board 20. |
