Abstract

A light emitting device includes a light emitting element, a wire connected to the light emitting element, and a substrate supporting the light emitting element. The substrate is formed with a first recess and a second recess that are open in a common surface of the substrate. The first recess includes a first bottom surface and a first side surface connected to the first bottom surface, and the light emitting element is disposed on the first bottom surface. The second recess includes a second bottom surface and a second side surface connected to the second bottom surface, and the wire is bonded to the second bottom surface. Both of the first side surface and the second side surface reach the common surface. The first side surface is connected to both of the second bottom surface and the second side surface. The opening area of the first recess is larger than the opening area of the second recess.
