Claim:
1. A method for producing an organic electroluminescent element, comprising a vapor deposition step of forming a patterned thin film by allowing vapor deposition particles to adhere to a substrate while moving the substrate relative to one or more vapor deposition sources, a limiting plate, and a mask, with the substrate being spaced from the mask, the one or more vapor deposition sources, the limiting plate, the mask, and the substrate being arranged in the stated order, the limiting plate being provided with openings, the one or more vapor deposition sources each being provided with ejection orifices that face the respective openings, the vapor deposition step including vapor deposition carried out under the condition of ri<Ri, the ejection orifices facing the same opening being spaced from each other to give a sum of distributions represented by the following formula (1) that is equal to or smaller than 1 (≦1), wherein Ri represents a maximum film-formation rate of an ejection orifice i among the ejection orifices facing the same opening, i represents an integer of 1 or greater and m or smaller, m represents the number of the ejection orifices facing the same opening, ri represents the actual film-formation rate of the ejection orifice i in the vapor deposition step, ni is an n value, which is zero or more, of the ejection orifice i, and θi represents an angle formed by a main film formation direction and a segment connecting the ejection orifice i and a point within the film formation region.
