The subject of the present invention is to provide an emission material which contributes to high emission efficiency, low drive voltage, excellent heat resistance and long life in an organic electroluminescent device, particularly an emission material which is excellent in emission of blue color. Further, the subject is to provide an organic electroluminescent device using the above emission material. The above subjects can be achieved by an emission material represented by Formula (1) and an organic electroluminescent device comprising the same.
