Abstract

A light emitting device includes a package having a recess which includes a bottom surface and an inner peripheral surface around a periphery of the bottom surface. The package includes a first lead to define a first part of the bottom surface, a second lead to define a second part of the bottom surface, and a resin body to provide the inner peripheral surface and a remaining part of the bottom surface. The bottom surface includes a light emitting element mounting region in the first part and a groove surrounding the light emitting element mounting region. A light emitting element is mounted on the light emitting element mounting region. A light-transmissive resin is provided in the recess to be in at least a part of a groove surface. A light reflecting resin is provided between the inner peripheral surface of the recess and the light-transmissive resin.
