Abstract: A light-emitting device includes a light-emitting element; one or more silver-based members having silver on their surfaces; and a resin layer including a first resin layer covering at least one of the silver-based members, and a second resin layer placed directly on the first resin layer. The light-emitting element is covered with the first resin layer or both the first resin layer and the second resin layer, at least one of the first resin layer and the second resin layer contains an inorganic adsorbent which chemically adsorbs a sulfide, the second resin layer contains a sulfide-based phosphor, and a ratio of a thickness of the first resin layer with respect to a total thickness of the first resin layer and the second resin layers is 50% or more.
