PROBLEM TO BE SOLVED: To provide an organic EL light-emitting element with high gas barrier properties or sealing characteristics of metal electrodes (4, 5) covering an organic EL film 3. SOLUTION: The organic EL light-emitting element includes a transparent substrate 1, a transparent first electrode 2 formed on a main surface of the substrate 1, an organic EL film 3 formed on the first electrode 2 emitting light by exciton generated by recombination with a hole and an electron injected into an organic compound, and second electrodes (4, 5) formed so as to cover a surface of the organic EL film 3. The second electrodes (4, 5) are provided with a first metal film 4 formed on the organic EL film 3 and a second metal film 5 formed on the first metal film 4. The second metal film 5 is an amorphous or a microcrystal metal film with less possibility that a grain boundary continues or penetrates on a surface and a rear face of the film as compared with a polycrystalline structure.
