An object of the present invention is to provide a method for an organic EL element in which the organic EL element can be readily produced by a roll to roll method, in the case where the respective components of the organic EL element are sequentially laminated from a cathode. A method for manufacturing an organic EL element of a preferable embodiment is a method for manufacturing an organic EL element by laminating, on a supporting substrate, a cathode, an electron injection layer, a light-emitting layer and an anode to manufacture an organic EL element by a roll to roll method, the manufacturing method including a step for forming an electron injection layer on the cathode of the supporting substrate on which the cathode has been formed, by applying an ink including an ionic polymer so as to form a film, a step for forming a light-emitting layer on the electron injection layer, and a step for forming an anode on the light-emitting layer. |
