Provided is a method for manufacturing an organic EL device, including: a vapor deposition step of forming an organic layer over a substrate moving relative to a nozzle by discharging a vaporized organic layer-forming material through the nozzle. The vapor deposition step is performed so that a light emitting region formed of the organic layer and having a width A (mm) in a direction perpendicular to a direction in which the substrate is moving is formed, and so that W≧A+2×h (where h≦5 mm) is satisfied, where a length of an opening of the nozzle in the direction perpendicular to the direction in which the substrate is moving is denoted by W (mm), and a distance between the opening and the substrate is denoted by h (mm).
