Abstract
A phosphor plate including: a complex containing an α-sialon phosphor and a sintered body containing spinel represented by a general formula M2xAl4-4xO6-4x (where M represents at least one of Mg, Mn, and Zn, and 0.2<x<0.6). In addition, there is provided a light emitting device including: a group III nitride semiconductor light emitting element; and the phosphor plate provided on one surface of the group III nitride semiconductor light emitting element. Further, there is provided a method for manufacturing the phosphor plate.
