<p>A highly reliable light-emitting device is provided, which is capable of effectively suppressing detrimental effects of sulfuric gas. A light-emitting device comprising a solid light-emitting element 1, a metal member 2 reacting with sulfuric gas and a phosphor-containing layer 5 that contains a phosphor 3, the phosphor-containing layer 5 containing a sulfuric gas-adsorbing substance 4 that adsorbs sulfuric gas, and, when the phosphor-containing layer 5 is tripartitioned from the side near the metal member to far into a proximal layer portion, an intermediate layer portion and an outer layer portion, the concentration of sulfuric gas-adsorbing substance 4 in the proximal layer portion is made to be higher than those for the intermediate layer portion and the outer layer portion.</p> |
