A light-emitting device is produced using a phosphor composition containing a phosphor host having as a main component a composition represented by a composition formula: aM3N2.bAlN.cSi3N4, where "M" is at least one element selected from the group consisting of Mg, Ca, Sr, Ba, and Zn, and "a", "b", and "c" are numerical values satisfying 0.2@a/(a+b)@0.95, 0.05@b/(b+c)@0.8, and 0.4@c/(c+a)@0.95. This enables a light-emitting device emitting white light and satisfying both a high color rendering property and a high luminous flux to be provided.
