[Task] An organic electroluminescent (EL) device having high efficiency, low operating voltage, and a long life is obtained by combining various materials for an organic EL device used as materials for an organic EL device with high efficiency and high durability in punched hole. and electron injection / transport properties, electron blocking ability, stability in a thin film state and durability are excellent, so that the respective materials can effectively exhibit their properties. [Means for realizing the task] In the organic EL device having at least one anode, a hole injection layer, a first hole transport layer, a second hole transport layer, a light emitting layer, an electron transport layer and a cathode therein In sequence, the second hole transporting layer includes an arylamine compound represented by the following general formula (1).
