Abstract
A method of manufacturing a light-emitting device including a light-emitting element which emits light with a predetermined wavelength and a wavelength conversion portion including a fluorescent substance which is excited by the light emitted from the light-emitting element to emit fluorescence with a wavelength different from the predetermined wavelength, includes the followings. First, spraying so as to apply a liquid mixture containing a layered silicate mineral and a translucent ceramic precursor on the light-emitting element from a nozzle is performed while the nozzle is moved relative to the light-emitting element. Subsequently, forming of the wavelength conversion portion by heating the sprayed and applied liquid mixture is performed.
