Abstract: A light-emitting device includes a light emitting element having a pad electrode, and a metal member connected to the pad electrode via a wire. The wire has a layered structure including at least a core material containing copper as a main component, an intermediate layer containing palladium as a main component, and a surface layer containing silver as a main component. The intermediate layer is art raged between the core material and the surface layer.
