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: aM3N2obAlNocSi3N4, 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. |
