An aromatic amine derivative having a specific structure. An organic electroluminescence device which is composed of one or more organic thin film layers including at least one light emitting layer sandwiched between a cathode and an anode, wherein at least one of the organic thin film layers contains the aromatic amine derivative or a material for the organic electroluminescence device singly or as its mixture component. They provide an organic electroluminescence device with an enhanced efficiency of light emission and having prolonged lifetime emitting blue light, a novel aromatic amine derivative and a material for the organic electroluminescence device realizing the device.
