The present invention provides a novel
aromatic amine derivative enabling to obtain an
organic electroluminescence device which is driven under a
low voltage, exhibits small increase in the driving
voltage after continuous driving for a long time and has a long life. The amine derivative is represented by the following general formula (1). In the formula, R1 to R7 each represent, for example,
hydrogen atom or a substituted or unsubstituted
aryl group having 5 to 50 nuclear carbon atoms; a represents an integer of 1 or greater; b, c, g and h each represent an integer of 1 to 5, and d, e and f each represent an integer of 1 to 4; and Ar1 and Ar2 represent a group represented by following general formulae (2) and (3), respectively, and the groups represented by Ar1 and Ar2 are not same with each other. R8 to R11 each represent, for example,
hydrogen atom; and i and m each represent an integer of 1 to 5, j and k each represent an integer of 1 to 4, n and p each represent an integer of 0 or greater, and n≠p.
