Abstract: A method of manufacturing a light emitting device, using a spray coating method, a fluorescent material can be easily adhered on corner portions and side surfaces of an LED chip, a lens-shaped light transmissive resin member surface, an optical lens surface, etc., and a spray coating machine used in the method. The method includes mounting an LED chip on a substrate member, applying a spray coating to a coating object including the LED chip by spraying a powder-containing solution. The applying a spray coating is performed such that a powder-containing solution is sprayed through a solution nozzle arranged above the coating object, as a spray direction of the powder-containing solution indicating a central axis, while using at least one gas nozzle arranged in a surrounding relationship to the central axis, spraying a gas toward the central axis to alter the direction of the spray made of the powder-containing solution.
