PURPOSE:To facilitate a wiring while ensuring sufficient electrical insulation and noise resistance by wiring a wire between arbitrary points by using a light- emitting module and a light-receiving module. CONSTITUTION:A light-emitting module 2 and a light-receiving module 2' on a printed substrate 11 are arranged so that light-emitting (receiving) sections 1, 1' for the modules are faced each other in a wiring between two points on the substrate 11. When a wire is wired optically between printed substrates 11, 11', light-emitting (receiving) modules 2, 2', bottoms thereof have light-emitting (receiving sections 1, 1', and light-receiving (emitting) modules 2, 2', upper sections thereof have light-receiving (emitting) sections 1, 1', are disposed to the substrates 11, 11' so that the light-emitting (receiving) sections 1, 1' are faced each other. When the light-emitting (receiving) sections 1, 1' cannot rectilinearly be faced each other, the light-emitting (receiving) sections 1, 1' are connected by an optical fiber rod 12. |
