Title:
Optical transmission module
Document Type and Number:
Japanese Patent JP6278826
Kind Code:
B2
Abstract:
Provided is an inexpensive and compact optical transmission module (10) having high coupling efficiency between an optical fiber (400) and a light projecting element (210) and/or a light receiving element (210). This optical transmission module (10) includes a lead frame (110) including an electric wiring pattern formed therein, a resin housing formed through insert-molding of the lead frame (110), and an electric device mounted on the lead frame (110) and including a light projecting element (210) for photoelectric conversion. The lead frame (110) forms a slit (112) positioning an optical fiber (400) to be coupled and a reflection mirror (116) reflecting and condensing light from the light projecting element (210) to the optical fiber (400). The lead frame is bent out of plane at the end of the slit receiving the fibre and thus forms the mirror.
