[PROBLEMS] To provide a package for light emitting element accommodation that realizes enhanced reflectance without application of a metal plating onto a ceramic. [MEANS FOR SOLVING PROBLEMS] There is provided a package for light emitting element accommodation comprising ceramic substrate (2) having conductor mounting region (8) for mounting of light emitting element (1) on its upper surface; frame (4) 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 (4) disposed on an upper surface of the substrate (2) in such a fashion that internal circumferential surface (7) of through-hole (3) expands outward; and light emitting element (1) mounted on the conductor mounting region (8) of the substrate (2). Thus, the reflectance of the frame (4) is enhanced without application of a metal plating thereonto.
