Disclosed is an organic electroluminescent device (organic EL device) which is improved in luminous efficiency, fully secured of driving stability, and of simple constitution. Also disclosed is a compound useful for the fabrication of said organic EL device. The organic electroluminescent device comprises organic layers including a light-emitting layer disposed between an anode and a cathode which are piled one upon another on a substrate and said organic layers comprise a compound represented by general formula (1). A light-emitting layer containing a phosphorescent dopant is suitable for an organic layer comprising a compound represented by general formula (1). In general formula (1), X is CR or N; Ar1 to Ar3 each is a substituted or unsubstituted aromatic hydrocarbon group or a substituted or unsubstituted aromatic heterocyclic group; Ar2, Ar3 and the nitrogen to which Ar2 and Ar3 are joined may together form a nitrogen-containing heterocyclic ring; m and n each is an integer of 1 or 2 and the sum of m and n is 3.
