PROBLEM TO BE SOLVED: To provide a triarylamine-based compound, and to provide an organic electroluminescent element using the same. SOLUTION: This triarylamine-based compound represented by the general formula (1) (Ar<SB>1</SB>to Ar<SB>8</SB>are each independently a substituted or non-substituted 6 to 30C aryl, or a substituted or non-substituted 6 to 30C heteroaryl), and used for organic electroluminescent elements, and an organic electroluminescent element adopting an organic film using the same. Thereby, the triarylamine-based compound can effectively be used as a hole-injecting and hole-transporting material suitable for fluorescent and phosphorescent elements for all colors such as red, green, blue and white colors on the basis of excellent electric characteristics and high electric charge transport ability, and enables the production of organic electroluminescent elements having high efficiency, low electric voltages, high luminance and long lives.
