An aromatic amine derivative having a terminal substituent selected from a dibenzofuran, a dibenzothiophene, a substituted carbazole and a substituted fluorene bound to the central skeleton having a specific structure through a nitrogen atom; and an organic electroluminescent element which comprises an cathode, an anode, and an organic thin film layer intercalated between the cathode and the anode and having at least one layer including at least a light-emitting layer, wherein at least one layer in the organic thin film layer contains the aromatic amine derivative as a sole component or contains a mixture containing the aromatic amine derivative, and which has a long service life and high light-emitting efficiency, and an aromatic amine derivative which enables the production of the organic electroluminescent element. |
