OPTICAL MODULE

摘要

An optical module is provided with a photoelectric conversion element (103) for alternately converting electric signals and optical signals, and an optical communication LSI (102) electrically connected with the photoelectric conversion element (103). The optical module is also provided with an electrical wiring board (101) which has a plurality of electrodes (201, 202) whereupon the photoelectric conversion element (103) and the optical communication LSI (102) are flip-chip mounted, and a plurality of wiring layers (101a, 101b, 101c) electrically connecting the electrodes (201, 202). The wiring layers (101a, 101b, 101c) are arranged on an upper plane, a lower plane and a side plane, respectively, in the electrical wiring board. On a side plane of the electrical wiring board (101), electrodes (201, 202) are arranged for coupling the photoelectric conversion element (103).
