An organic EL element (1A) is provided with a transparent substrate (10), a first transparent electrode layer (11), an organic electroluminescent layer (12), a second transparent electrode layer (13), and a reflecting layer (14). The refractive index of the transparent substrate (10) is lower than the refractive index of any film included in the organic electroluminescent layer (12), and both the refractive index of the first transparent electrode layer (11) and the refractive index of the second transparent electrode layer (13) are lower than the refractive index of any film included in the organic electroluminescent layer (12). |
