An aromatic amine derivative represented by the general formula (1). In the general formula (1), R 1 -R 5 and R 7 -R 11 are each independently hydrogen atoms or substituents. In the general formula (1), R 6 and R 12 are represented by the general formula (2); L 1 -L 3 are each independently a single bond, divalent residue of an aryl group, or the like. In general formula (2), Ar 1 is a monovalent substituent having the general formula (3) as a partial structure; X is an oxygen atom or a sulfur atom. In general formula (2), Ar 2 is a substituted or unsubstituted aryl group, or the like. |
