A triphenylamine derivative represented by formula (1) exhibits good solubility in an organic solvent and allows an organic EL element having excellent luminance characteristics to be achieved when formed into a thin film and applied to a positive hole injection layer. (In the formula, R 1 to R 17 mutually independently represent a hydrogen atom, a halogen atom, a nitro group, a cyano group, an amino group, an aldehyde group, a hydroxyl group, a thiol group, a carboxylic acid group, and the like; and 1, m, and n mutually independently represent an integer 1 to 5.) |
