Abstract
To provide a package for light emitting element accommodation that realizes enhanced reflectance without application of a metal plating onto a ceramic. There is provided a package for light emitting element accommodation comprising ceramic substrate () having conductor mounting region () for mounting of light emitting element () on its upper surface; frame () of a light reflecting material containing 74.6 mass % or more of alumina whose average particle diameter after sintering is 2.5 μm or less, the frame () disposed on an upper surface of the substrate () in such a fashion that internal circumferential surface () of through-hole () expands outward; and light emitting element () mounted on the conductor mounting region () of the substrate (). Thus, the reflectance of the frame () is enhanced without application of a metal plating thereonto.
