Abstract: A method of manufacturing a semiconductor light emitting device, includes forming a conductive film on a surface of a semiconductor light emitting element. Phosphor particles are charged by mixing phosphor particles with an electrolyte having a metallic salt dissolved therein. The semiconductor light emitting element having the conductive film formed thereon is immersed in the electrolyte having the charged phosphor particles. A phosphor layer on the conductive film is formed by electrophoresing the phosphor particles. The conductive film is removed using wet etching.
