Abstract: Provided is a light-emitting device that has excellent light extraction efficiency, inhibits deterioration of light-emission characteristics over time, and can be easily produced. The light-emitting device includes a substrate, a solid-state light-emitting element mounted on the substrate, a circular tube-shaped member positioned on the substrate such as to surround the solid-state light-emitting element, and a transparent resin portion including a cylindrical section that encapsulates the solid-state light-emitting element and that is in contact with an inner surface of the circular tube-shaped member, and a dome-shaped section that is positioned above the cylindrical section. The inner surface of the circular tube-shaped member is water repellent. The dome-shaped section contains a phosphor that is excited by light of a light-emission wavelength of the solid-state light-emitting element.

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.
