One or more one-dimensional array-shaped photoelectric conversion modules 302 are mounted on a board 301. A one-dimensional array-shaped light receiving/emitting element 303 is mounted in each of the one-dimensional array-shaped photoelectric conversion modules 302. Further, the one-dimensional array-shaped photoelectric conversion modules 302 are mechanically and optically connected to a flexible fiber sheet 306 through an optical connector 305. As parallel transmission paths 306 from the one-dimensional array-shaped photoelectric conversion modules 302 approach an end of a board 301, they are laminated with each other and connected to a two-dimensional array-shaped optical connector 307 at an end of the board. Further, a wavelength multiplexer/demultiplexer is connected to the optical connector.
