PROBLEM TO BE SOLVED: To provide an organic electroluminescent element that has low driving voltage, high current efficiency, and high voltage efficiency.SOLUTION: An organic electroluminescent element comprises an anode and a cathode, and an organic layer arranged between the anode and cathode. The organic layer is a layer including: a mixed layer including a luminescent low-molecular-weight compound and/or charge transport low-molecular-weight compound in a film including an insoluble polymer formed by making an insolubilization polymer insoluble and a layer adjacent to the mixed layer and including the luminescent low-molecular-weight compound and charge transport low-molecular-weight compound but not including the insolubilization polymer. The insolubilization polymer is either a dissociation polymer or desorption polymer.
