Abstract: An object is to improve use efficiency of an evaporation material, to reduce manufacturing cost of a light-emitting device, and to reduce manufacturing time needed for a light-emitting device including a layer containing an organic compound. The pressure of a film formation chamber is reduced, a plate is rapidly heated by heat conduction or heat radiation by using a heat source, a material layer on a plate is vaporized in a short time to be evaporated to a substrate on which the material layer is to be formed (formation substrate), and then the material layer is formed on the formation substrate. The area of the plate that is heated rapidly is set to have the same size as the formation substrate and film formation on the formation substrate is completed by one application of heat.
