An aromatic amine derivative including a substituent A and a substituent B each represented by the formula (1) or (2) and having an arylene group bound to a carbazole structure, in which the substituent A and the substituent B include groups different from each other in the position at which the arylene group is bonded to the carbazole structure, and the substituent A and the substituent B are bonded to the same nitrogen atom or different nitrogen atoms in the molecule; an organic electroluminescent device including an organic thin-film layer formed of one or more layers including at least a light emitting layer, the organic thin-film layer being interposed between a cathode and a anode, in which at least one layer of the organic thin-film layer contains the aromatic amine derivative, and the molecules are rarely crystallized.
