PURPOSE : A manufacturing method of a nitridosilicate based compound is provided to provide nitridosilicate with economic and excellent phosphor performance by using a simple device under atmospheric pressure, low reaction temperature, and relatively short reaction time by a process of a one step. CONSTITUTION : A manufacturing method of a nitridosilicate based compound comprises : a step of obtaining a mixture by mixing an alkaline earth metal compound, a rare earth metal compound, a silicon compound, and a nitrogen compound for 2-24 hours; a step of heat-treating the mixture at 1200-2000 °C for 1-24 hours in gas having a gas flow rate of 1-1000 mL/minute under atmospheric pressure. The alkaline rare earth metal compound is at least one or more selected from oxide of alkaline rare earth metal, oxide, sulfide, chloride, bromides, iodide, carbonate, organic/inorganic acid salts, and nitrates.
