PROBLEM TO BE SOLVED: To provide a light-receiving electromotive device for converting light transmitted from an optical fiber to electric power effectively. SOLUTION: A light receiving electromotive device 41 includes two or more power feeding light-receiving electromotive elements 43 connected in parallel. The power feeding light-receiving electromotive element 43 generates power from light that is transmitted from a laser light source 10 through an optical fiber. In this case, the optical fiber 26 is branched into two or more, and each light receiving electromotive element is preferably irradiated with the light from the output terminal that corresponds to each branch of the optical fiber. |
