PROBLEM TO BE SOLVED: To provide an organic electroluminescent element of high efficiency and brightness by reducing the electric resistance of an anode, and inhibiting voltage drops and heating when a large current flows through it. SOLUTION: A thin film of ITO is formed on the surface of a transparent substrate 1 by deposition or sputtering to form a transparent electrode (anode) 2. An organic light emitting layer 3 is provided on the upper surface of the transparent electrode 2. Further, a thin film made from a cathode material is formed on the upper surface of the organic light emitting layer 3 by deposition or sputtering to produce a cathode 4. An auxiliary electrode 5 having a high electrical conductivity is provided which is not coplanar with the organic light emitting layer 3 on the transparent electrode 2.
