Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an inexpensive optical transmission module by configuring to use a type of photodetector with two electrodes on top. SOLUTION: The optical transmission module includes: a lead frame (housing) 3 having an opening at a position oppositely facing the optical axis of an optical fiber 4; a raised section 3a for which a part of the bottom of the lead frame 3 is cut and raised to constitute a slope that forms a prescribed angle with the optical axis; a reflection type shielding filter 2 mounted on the slope of the raised section 3a to reflect only the light with a signal wavelength λ1; and such photodetector 1 of a type with two electrodes on top that is mounted, with the light receiving face down, in the opening on the lead frame 3.
