A novel nitrogen-containing heterocyclic derivative having a specific structure. An organic electroluminescence device comprises an organic thin-film layer which is disposed between a cathode and an anode and comprises one or more layers having a light emitting layer. At least one layer of the organic thin-film layer comprises the nitrogen-containing heterocyclic derivative. The organic electroluminescence device exhibits a high luminance and a high luminous efficiency even at a low driving voltage.
