Disclosed is a method for producing a light-emitting body having high luminance and long life. Also disclosed are a light-emitting body and a light-emitting device, specifically an inorganic EL device wherein a backside electrode, a dielectric layer, a light-emitting layer, a dielectric layer and a transparent electrode are sequentially arranged in this order. The light-emitting body is produced by mixing an activator containing Pr, Mn and Au into strontium sulfide (SrS) as the host material, heating the resulting for activating the host material, and then adding GaAs and InP thereinto and firing the resulting in a nitrogen atmosphere containing a sulfur gas. A light-emitting layer can be obtained by mixing the thus-produced light-emitting body with a ultraviolet-curable dielectric substance.
