Abstract

A method of manufacturing an organic EL element includes: a first step of forming a lower electrode on a substrate; a second step of forming an organic functional layer on the lower electrode; and a third step of forming an upper electrode on the organic functional layer, wherein the third step includes: a first film-forming step of forming a thin film on the organic functional layer by magnetron sputtering, the thin film being formed of material of the upper electrode; and a second film-forming step of forming, after the first film-forming step, another thin film by a film-forming process different from the magnetron sputtering on the thin film formed in the first film-forming step, said another thin film being formed of the material of the upper electrode.
