Provided is an organic electroluminescent element that maintains higher hole injection characteristics than conventional organic EL elements. This organic electroluminescent element has an organic compound layer sandwiched between a positive electrode and negative electrode. The organic compound layer contains at least a light emitting layer and charge generating layer and is characterized by (1) having a charge generating layer formed from at least one layer between the positive electrode and the light emitting layer and (2) containing an organic metal complex in at least one of the charge generating layer.
