1. An organic electroluminescence material being a compound represented by Formula (1), wherein A and B each represent a 6-membered aromatic hydrocarbon group, or a 5- or 6-membered aromatic heterocyclic group, provided that at least one of A and B represents a 5-membered aromatic heterocyclic group; Q represents a substituent having a vacant orbital which is capable of accepting a π electron from A or B; M represents a transition metal element belonging to groups 8 to 10 in the periodic table; L represents a ligand which is capable of coordinating with M; m1 is an integer of 1 to 3; m2 is an integer of 0 to 2; and n is an integer of 1 to 4, and wherein the substituent Q represents one selected from the group consisting of Q-1, Q-2 and Q-3, wherein Ar1 and Ar2 each respectively represent an aromatic hydrocarbon ring group or an aromatic heterocyclic group, provided that Ar1 and Ar2 may be joined to form an aromatic ring; Ra, Rb and Rc each represent an alkyl group, a cycloalkyl group, an aromatic hydrocarbon ring group or an aromatic heterocyclic group; J1, J2 and J3 each represent an arylene group or a heteroarylene group; and r, s and t each represent an integer of 0 or 1.
