Provided is an organic electroluminescence element in which drive voltage increases and short circuits are unlikely to occur, not only in room-temperature environments, but also in high-temperature environments, and which has outstanding long-term durability and lifespan characteristics. The organic electroluminescence element is provided with a plurality of light emitting layers (4, 5) stacked, with an intermediate layer (3) interposed therebetween, between a positive electrode (1) and a negative electrode (2). In the intermediate layer (3), a first layer (3a) that includes a nitrogenous heterocyclic ring compound, an alkali metal layer (3b) comprising an alkali metal, a second layer (3c) that includes a nitrogenous heterocyclic ring compound, and a hole injection layer (3d) that comprises electron-accepting organic matter are formed in this order from the positive electrode (1) side to the negative electrode (2) side. The second layer (3c) is thicker than the alkali metal layer (3b). |
