[Object] An object of the present invention is to provide, as a material for an organic EL device having high efficiency and a high durability, a material for an organic EL device having excellent injection/transport performance of holes, excellent electron blocking capability, excellent stability in a thin-film state, and an excellent durability, and to further provide an organic EL device having high efficiency, a low drive voltage, and a long lifetime by combining the material and various materials for an organic EL device having excellent injection/transport performance of holes and electrons, excellent electron blocking capability, excellent stability in a thin-film state, and an excellent durability so that the properties of the respective materials can be effectively exhibited. [Solving Means] Since an arylamine compound having a specific structure in the present invention has excellent injection/transport performance of holes, excellent stability in a thin-film state, and an excellent durability, holes injected from the anode side can be effectively transported by selecting this arylamine compound having a specific structure as a material of a hole transport layer. Further, various organic EL devices obtained by combining an electron transport material having a specific structure and the like exhibit favorable device properties.
