Zusammenfassung:It is an object of the present invention to provide a polymer organic EL element that has a low driving voltage, high light emission efficiency, and a long lifespan. The present invention provides an organic electroluminescence element having a pair of electrodes and at least one organic layer between the electrodes, wherein the organic layer is constituted by two or more high molecular weight compounds including at least high molecular weight compounds α and β, and the high molecular weight compound α has a substituted triarylamine structural unit represented by a general formula (1) below and has a weight average molecular weight of 10,000 or more and less than 1,000,000 in terms of polystyrene. For the symbols in the formula, see the Description.
