PROBLEM TO BE SOLVED: To provide an organic EL element of a long life having both of merits inherent in an organic material and an inorganic material, improved in efficiency, and having a low operation voltage, in particular practically valuable for a flat type color display of high performance. SOLUTION: This element is an organic EL element having a hole implantation electrode 2 and an electron implantation electrode 3 on a substrate 1, and having an organic layer 5 concerned at least in a luminous function between the electrodes 2, 3, and has an inorganic insulated electron implantation layer 4 in which cerium oxide is contained between the electrode 3 and the organic layer 5, to be acceptably added with one kind or more of a stabilizing component or a work function regulating component additionally.
