An aromatic amine derivative represented by general formula (1). In general formula (1), R1 to R10 each independently are a hydrogen atom or substituent group. In general formula (1), R1 is represented by general formula (2), and any one of R2 to R5 and R7 to R10 is represented by general formula (2); L1 to L3 each independently are a single bond, a bivalent residue of an aryl group, or the like. In general formula (2), Ar1 is a monovalent substituent group having general formula (3) as a partial structure, X is an oxygen atom or a sulfur atom, and A and B represent six-membered rings. In general formula (2), Ar2 is an aryl group, a monovalent substituent group having general formula (3) as a partial structure, or the like. |
