Disclosed is an organic electroluminescence device which can be stably produced by a wet process and exhibits enhanced external quantum efficiency and reduced coating unevenness and a production method thereof. Specifically, disclosed is a method of producing the organic electroluminescence device comprising at least a layer, which is formed by a wet process comprising of coating a solution of an organic material dissolved in a solvent to form a liquid layer, followed by removal of the solvent by blowing air to form the layer, wherein the relative drying rate of the solvent to butyl acetate is from 1 to 1000, (based on the drying rate of butyl acetate being 100), the thickness of the formed liquid layer is from 1 to 100 μm, a air-blowing rate is from 0.1 to 5 m/s and the time between completion of coating and start of blowing is from 0 to 60 sec.
