The object of the present invention is to provide a method of stably producing a high quality organic EL device by surely avoiding adverse influence due to organic matters and the like when an organic layer is formed on a surface of, for example, a substrate having an anode formed thereon. The means for resolution is characterized in that the inside of an organic EL device production apparatus equipped with an organic film-forming chamber for forming an organic layer on a surface of, for example, a substrate having an anode formed thereon is cleaned with an ozone gas, and the organic layer is then formed.
