PURPOSE:To fix individual components on a substrate one by one, and to eliminate the need for optical axis alignment by aligning the optical axes of optical terminals with signal converters and coupling the optical terminals with the end surface of an optical waveguide optically, and connecting an electric circuit component to electric conductors on the substrate. CONSTITUTION:This device is provided with at least an electric circuit component 3, the signal converters 4 and 6 which are connected electrically to the electric circuit component 3 and perform conversion between a light signal and an electric signal, and an electric terminal 15 which is connected electrically to the electric conductors on the substrate 10. Further, the optical terminals 5 and 7 are coupled optically with the end surface of the end surface 14 of the optical waveguide 12 provided on the substrate 10 while having their optical axes aligned with the signal converters 4 and 6. Consequently, the individual components such as a light receiving element 14, a light emitting element 6, the electric component 3, and a converging rod lens are fixed on the substrate one by one, to eliminate the need for optical axis alignment. |
