The present invention provides a method for producing a phosphor which can obtain a (Sr, Ca) AlSiN 3 -based nitride phosphor having higher productivity and higher reliability than conventional ones using a nitride raw material. (Sr, Ca) AlSiN 3 crystal, wherein the raw material is mixed and a sintering step of sintering the mixture obtained by the mixing step is carried out to produce a phosphor having a crystal structure substantially identical to that of the (Sr, Ca) SrN, Sr 2 N or a mixture thereof and a nitrogen content of 5 to 12 mass% is used as the main crystal phase in the crystal phase analysis by the powder X-ray diffraction method. |
