PROBLEM TO BE SOLVED: To obtain an organic electroluminescent element emitting blue phosphorescence in high efficiency. SOLUTION: In the organic electroluminescent element supporting an organic thin film layer composed of one or a plurality of layers containing at least a light emitting layer between a minus terminal and a plus terminal, at least one layer of the organic thin film layers contains a nonionic cyclic polynuclear gold complex.
