Provided are: a novel aromatic amine derivative having an asymmetric structure; and an organic electroluminescence device having one or multiple organic thin film layers including at least a light emitting layer, the one or multiple organic thin film layers being interposed between a cathode and an anode. The aromatic amine derivative realizes the organic EL device capable of suppressing the crystallization of a molecule, improving yields upon production of the organic EL device, and having a long lifetime when at least one layer of the one or more multiple organic thin film layers contains the aromatic amine derivative alone or as a component of a mixture.
