This invention provides a process for producing an organic EL element that, in forming, by a coating method, an organic EL element comprising a substrate bearing a plurality of organic EL elements each comprising at least a first electrode, one or more organic compound layers, a second electrode, and a sealing layer, can easily form an external connection terminal forming part for external connection terminal formation and can realize high production efficiency and stable performance quality. The process for producing an organic EL element is a process for producing an organic EL element comprising a substrate bearing at least one organic EL element comprising at least a first electrode (an anode layer), at least one organic compound layer, a second electrode (a cathode layer), and a sealing layer and is characterized by comprising a masking member application step of laminating a masking member having an adhesive strength of 1 N/25 mm to 10 N/25 mm onto the organic compound layer formation prohibition region on the substrate, an organic compound layer formation step of forming the organic compound layer on the substrate, and a masking member separation step of separating the masking member.
