PROBLEM TO BE SOLVED: To provide a light source device which can output a plurality of kinds light by using a plurality of light-transmitting media and can supply light of enough intensity to each light-transmitting medium. SOLUTION: An organic EL element is formed at a side face by laminating in turn a transparent electrode layer 14 as a positive electrode, an organic compound layer 16 including a luminous layer, and a metal electrode layer 18 as a negative electrode, and a plurality of fibers 12 propagating light guided inside from the organic EL element 20 to an axis direction are aligned in an array state and fixed with a conductive binder 22, and are then made pinched by two common electrode plates 24, so that a common voltage can be impressed on the organic EL elements 20 of the plurality of the fibers 12. Further, an exposed part 14A of the transparent electrode is provided at an end on the light-incident side of each fiber 12, so that voltage can be impressed on an anode electrode independently for each organic EL element 20 of the plurality of the fibers 12. |
