Aromatic amine derivative and organic electroluminescent element using same

An aromatic amine derivative represented by the following formula (1):

• wherein R1 to R8 are independently a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms, a substituted or unsubstituted cycloalkyl group having 3 to 10 carbon atoms, a substituted or unsubstituted alkylsilyl group having 3 to 30 carbon atoms, a substituted or unsubstituted arylsilyl group having 8 to 30 ring carbon atoms, a substituted or unsubstituted alkoxy group having 1 to 20 carbon atoms, a substituted or unsubstituted aralkyl group having 6 to 20 ring carbon atoms, or a substituted or unsubstituted aryl group having 6 to 10 ring carbon atoms,
• at least one of R1 to R8 is a group other than a hydrogen atom, and
• Ar1 to Ar4 are a substituted or unsubstituted aryl group having 6 to 30 ring carbon atoms, at least one of Ar1 to Ar4 is an aryl group substituted with one or more substituents selected from a cyano group, a fluorine atom, a halogenated alkyl group, a nitro group and a carbonyl group,
• provided that, when at least one of Ar1 to Ar4 is a p-fluorophenyl group, at least one of Ar1 to Ar4 which are not a p-fluorophenyl group is an aryl group other than a p-fluorophenyl group which is substituted with one or more substituents selected from a cyano group, a fluorine atom, a halogenated alkyl group, a nitro group and a carbonyl group.
