It is an object of the present invention to provide an arylamine compound which has resistance to repeated oxidation reactions. The present invention provides a secondary arylamine compound represented by General Formula 1. n n(In the formula, Ar 11 is an aryl group having 7 to 25 carbon atoms or a heteroaryl group having 7 to 25 carbon atoms. Ar 12 and Ar 13 may be identical or different, and are individually either an aryl group having 6 to 25 carbon atoms or a heteroaryl group having 5 to 9 carbon atoms. X is either a bivalent aromatic hydrocarbon group having 6 to 25 carbon atoms or a bivalent heterocyclic group having 5 to 10 carbon atoms.) |
