A main object of the present invention is to provide an organic EL element which can absolutely segment cathodes when forming an organic layer by a coating method, and a producing method thereof. The present invention attains the object by providing a producing method of an organic EL element comprising steps of: an organic layer forming step, in which at least one organic layer out of organic layers, including a light emitting layer, constituting an organic EL layer is formed by either of a printing method, a discharge method, or a transfer method on a substrate for an organic EL element, wherein the substrate for an organic electroluminescence element comprises a substrate, a first electrode layer formed on the substrate, plural insulating banks formed on the substrate on which the first electrode layer is formed and setting a segmentalized region which segments a second electrode layer into plural pieces, and wherein each of the banks has plural small banks provided in parallel with a predetermined gap; and a step of controlling a gap between the small banks such that, a height t1 of an end part of the organic layer at a side of a light emitting region of the small bank provided on the light emitting region side is higher than a height t2 of an end part of the organic layer at a side opposite to the side of the light emitting region of the small bank provided on the light emitting region side is.
