Provided is a high-luminance, long-life laminated organic electroluminescent element. The organic electroluminescent element has a composition in which a plurality of light-emitting units, including at least one organic light-emitting layer, are laminated between a positive electrode and a negative electrode, and in which a linking layer is held between the respective light-emitting units. The linking layer is formed by laminating, in succession from the positive electrode side, an electron generating/transport section, an intermediate layer, and a hole generating/transport section, which contain at least one metal selected from a group consisting of an alkali metal, alkaline earth metal, rare earth metal, alloy of these metals, and compound of these metals. Preferably the intermediate layer contains an electrical insulating non-semiconductive substance having a specific resistance which is between 1.0&#xd7;10&#x3a9;&#xb7;cm and 1.0&#xd7;10&#x3a9;&#xb7;cm.
