PROBLEM TO BE SOLVED: To provide an optical module which eliminates the need to precisely position optical fiber and photodetector without deteriorating the photodetection performance as to an optical module which couples optical fiber end surface with a photodetector and performs photoelectric transduction. SOLUTION: On a photodetector formation member 2, many photodetectors 6 whose lateral width is nearly as large as or smaller than the diameter of an optical fiber are arrayed closer than the intervals of V grooves 5 on an optical fiber holding member 1 where optical fibers 3 and fixed, so that there are plural photodetectors 6 positioned at the part of projection light from an optical fibers 3. Further, the optical fiber holding member 1 is only assembled without being positioned precisely on the photodetector member 2 to electrically couple plural electrodes 7 of the photodetectors 6 on which the light from the same optical fiber 3 is made incident electrically with a pattern 4 for electric connection, thereby obtaining the optical module which can obtain sufficient electric output as the signal of the optical fiber. |
