A method of manufacturing an organic electroluminescence element having on a belt-formed flexible base material, a first electrode, at least one organic functional layer, and a second electrode, includes continuously forming at least one organic functional layer by coating the same on a first electrode which is formed continuously on the flexible base material in the conveying direction thereof, further forming a second electrode on the organic functional layer, so as to make a plurality of organic electroluminescence element structures in the conveying direction, and then cutting the electroluminescence element structures into individual organic electroluminescence elements so as to manufacture organic electroluminescence elements.
