Title: Optical module
Inventor: KUBO SHINICHI
IPC: H01L31/02
Filed: 1995-12-19
Abstract: PROBLEM TO BE SOLVED: To prevent lowering of characteristic and sensitivity of an optical module inspite of using in a high-temperature atmosphere by tilting a lead guiding face of an optical unit exposed in an optical unit-inserting recess to the base of the optical unit so as to reflect extraneous light on the base of the tilting optical unit. SOLUTION: A resin mold 22 is so formed that a guiding surface of a lead 3 being its base may have a slant surface. In an optical module 31, light comes to be sent and received through the base of the recessed part between optical fibers and optical elements. At this time, since the guiding surface of the lead 3 of the resin mold 22 tilts to the base of housing 12, extraneous light 35 being incident from an opening part of the recessed part 13 and directed to the guiding surface of the exposed lead 3 reflects toward the wall surface of the recessed part 13 of the housing 12 so as to become not influencing on sending and receiving of light. Accordingly, black resin application for the external optical elements become needless thus obtaining good heat dissipation.
