A light emitting device, which can be efficiently manufactured and maintain a stable light emitting property for a long period, is provided. The light emitting device comprises a first resin forming body including a periphery that forms a recess to house a light emitting element and a bottom that forms a bottom portion of the recess, and a second resin forming body which covers the light emitting element. The first resin forming body is composed of a thermosetting epoxy resin composite whose essential component is an epoxy resin. The bottom covers surfaces of lead frames excluding mounting regions of the light emitting element and wires. A thickness of the bottom is formed thinner than a thickness from the surface of the lead frames to a leading end of the light emitting element.
