Abstract
In a submount main body () composed of a single crystal silicon, a mounting surface () on which a light-emitting device () is mounted is composed of a ()-oriented surface and the inner surface of a through hole () which is formed by anisotropic etching is parallel to the ()-oriented surface. The light-emitting portion of the light-emitting device () is arranged to face a device-side opening () which opens into the mounting surface () of the submount main body (). Consequently, heat generated in the light-emitting device () can be discharged to the outside more efficiently than the case where the light-emitting portion is arranged to face a side opposite to the submount side. Specifically, light from the light-emitting device () is reflected by a reflective surface formed on the surface of the through hole (), and highly efficiently transmitted outside of the submount main body ().
