Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a manufacturing method of an organic EL element capable of shortening an inspection time of a failed ejection nozzle of an ink jet. SOLUTION: In the ejection inspection method in which a water-repellent film having hydrophilic openings corresponding to respective ink-jet nozzles are formed in an ejection inspection region and the ink is applied from each of the nozzles with the openings as a target position and the failed ejection nozzles are identified based on an existence of filled ink in the openings, a reflectance of the opening and the water-repellent film becomes small if the ink is filled in the opening, and an inspection time can be shortened by inspecting the failed ejection nozzles.
