    摘要： Provided are an organic electroluminescence device that not only provides high efficiency but also has a long lifetime, and an aromatic amine derivative that realizes the device. The organic electroluminescence device includes an aromatic amine derivative, including at least one substituent A having dibenzofuran and at least one substituent B selected from groups each having dibenzofuran or carbazole, in a molecule thereof, in which the substituent A and the substituent B include groups different from each other, and the substituent A and the substituent B are bonded to the same nitrogen atom, or different nitrogen atoms, in the molecule. The molecules of the aromatic amine derivative hardly crystallize, which improves a yield in the production of the organic electroluminescence device. In the organic electroluminescence 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 an anode, the aromatic amine derivative is contained in at least one layer, particularly a hole transport layer, in the organic thin film layer.
