Abstract: An organic electro-luminescence (EL) element includes a first electrode, a light emitting layer, and a second electrode layered in this order above a substrate. At least one of the first electrode and the second electrode is a light transmissive electrode. The light transmissive electrode includes a base metal layer and a silver thin film. The base metal layer is a metal layer including an alkali metal or an alkaline earth metal as a material. The silver thin film is silver or a silver alloy including silver as a main component, and is disposed on and in contact with the base metal layer.
