Claim:
1. A light emitting device, comprising: an element mounting substrate with a circuit pattern at least on an element mounting surface of the element mounting substrate; a light emitting element mounted on the element mounting surface of the element mounting substrate and connected with the circuit pattern; a sealing member that seals the light emitting element on the element mounting surface; and a coating layer that covers an element mounting side of the element mounting substrate, the coating layer being disposed on the element mounting surface of the element mounting substrate, wherein the coating layer has a refractive index smaller than that of the sealing member, and wherein a joint interface between the sealing member and the coating layer is formed at a position to which light rays emitted from the light emitting element to the sealing member in a lateral direction or obliquely downward with respect to a central axis of the light emitting element reach.
