ABSTRACT:
A light-emitting element 22 and a light-receiving element 26 are attached to a circuit board so as to oppose each other across the circuit board 2. As a result, light from the light-emitting element 22 arrives at the light-receiving element 26 via the substrate 2. Since the distance between the light-emitting element 22 and the light-receiving element 23 thus becomes very short, the light conversion efficiency is improved by a wide margin. Further, since the substrate 2 is interposed between the light-emitting element 22 and the light-receiving element 26, the elements are completely isolated within the insulation breakdown voltage of the material constituting the substrate.
