A method of producing an organic EL element according to the present invention is a method of producing an organic electroluminescent element by stacking at least an anode, a cathode, and an organic light-emitting layer disposed between the anode and the cathode. The method includes an organic light-emitting layer formation step for forming the organic light-emitting layer by applying an organic light-emitting ink having an organic light-emitting material and a solvent to a light-emitting layer formation region on which the organic light-emitting layer is to be formed, by using a relief printing plate that has a relief portion in a shape corresponding to the shape of light-emitting layer formation region and has a plurality of grooves formed on a surface portion of the relief portion. According to the method of the present invention, coating unevenness when the region for forming a large area of organic light-emitting layer is coated with the organic light-emitting ink by using a relief printing method can be prevented, and thus the organic light-emitting layer with a uniform thickness can be formed.
