    • PROBLEM TO BE SOLVED: To provide a light-emitting device utilizing electroluminescence where extraction efficiency of luminescence is improved. SOLUTION: The light-emitting device includes a first light-emitting portion and an optical waveguide portion. The first light-emitting portion has an electroluminescence layer. The optical waveguide portion has a core and a clad. On a part of the core, a second light-emitting material, which absorbs a first light emitted from the first light-emitting portion for second light emission, is arranged with the light extraction surface facing the clad, and the first light-emitting portion is so arranged to cover a side surface of the optical waveguide portion containing a core region having the second light-emitting material with at least two flat surfaces, or so arranged as to surround the outer periphery of the optical waveguide containing the core region having the second light-emitting material, and further includes a light reflecting means covering the outer periphery of a combination region of the first light-emitting portion and the optical waveguide portion.
