The present invention provides a yellow phosphor having a higher emission intensity (luminance). In the present invention, a raw material mixture containing M 1 , M 2 , and L is baked while being brought into contact with a Si-containing gas containing Si in a gas phase, and M 1 2a (M 2 b L c ) M is obtained. containing 3 d O 4 in step to produce a yellow phosphor represented, is a manufacturing method of the yellow phosphor. M 1 is at least one element selected from alkali metals, M 2 is at least one element selected from alkaline earth metals, M 3 is Si, or Si and Ge, L Is at least one element selected from rare earth elements, Bi and Mn. a is 0.1 to 1.5, b is 0.8 to 1.2, c is 0.005 to 0.2, and d is 0.8 to 1.2. is there.
