An amine derivative represented by the following general formula (1) and exhibiting a temperature difference of 30°C or more as defined by the difference of [decomposition temperature (°C) minus sublimation temperature (°C)]: wherein R1 and R2 independently represent a substituted or unsubstituted C6-14 aryl or C5-40 heteroaryl group; and R3 and R4 independently represent a hydrogen atom, a straight-chain, branched or cyclic C1-18 alkyl or C1-18 alkoxy group, or a substituted or unsubstituted C6-40 aryl or C5-40 heteroaryl group, provided that R3 and R4 may form together a cyclic hydrocarbon group. The amine derivative is useful as an organic electroluminescent material.
