PROBLEM TO BE SOLVED: To provide a compound excellent in charge transport property and amorphous property and having a high glass transition temperature, and a charge transport material, an organic electroluminescent element material and an organic electroluminescent element using the same. SOLUTION: An aluminum mixed ligand complex compound represented by the following general formula (I), a charge transport material containing the compound, an organic electroluminescent device material, and an organic electroluminescent device. (Wherein the carbon atoms constituting the quinolinol skeleton are both good .Ar 1 be substituted with any group represents an aromatic hydrocarbon ring optionally having a substituent, Ar 2 is substituted Represents a polycyclic aromatic hydrocarbon ring which may have a group.)
