Abstract: A method of manufacturing a surface-treated phosphor (11) in which the surface of an alkaline-earth silicate phosphor (12) containing a silicate of alkaline-earth metal is covered with a surface treatment layer (13), the method comprising: surface treatment which brings the alkaline-earth silicate phosphor (12) into contact with the surface treatment substance (23) molten or pyrolyzed to form the surface treatment layer (13) on the surface of the alkaline-earth silicate phosphor (12) wherein the surface treatment substance (23) is at least one selected from a group consisting of a sulfate, a phosphate, a carbonate, a borate, a boric acid, a titanate, and a fluoride.
