PROBLEM TO BE SOLVED: To provide an organic electroluminescence element to make light emission at a high light emission efficiency and capable of being driven at a low voltage, in particular even in the blue region, emitting the light at a high light emission efficiency, and having a high durability even when light emission is made with a high brightness. SOLUTION: The organic electroluminescence element includes a light emitting layer formed between an anode and cathode through an evaporation process, wherein the light emitting layer has an adjoining layer containing at least one sort of light emitting material which makes light emission in the triplet excited condition and located adjacent to at least either of the anode side and cathode side of the light emitting layer, and the adjoining layer contains a conductive highpolymer.
