<P>PROBLEM TO BE SOLVED: To efficiently radiate the light emitted by a light-emitting element to the outside of the package for housing the light-emitting element by effectively preventing the light from being absorbed by a base and a frame of the package and to satisfactorily reflect the light to the outside of the package. <P>SOLUTION: The package for housing the light-emitting element comprises a base 1 of an almost rectangular parallelepiped, composed of white ceramics and having a mounting part 1a for mounting the light-emitting element 3 on the upper face of the base 1, and a frame 2 composed of white ceramics and joining the upper face of the base 1 so as to surround the mounting part 1a, wherein the base 1 has a thickness of ≥0.8 mm and has reflectivity of ≥80% for light of a wavelength of between 400 nm and 700 nm, and the inner circumferential face of the frame 2 is coated with a metal layer 6 whose reflectivity of the surface for the light is ≥80%. <P>COPYRIGHT: (C)2004,JPO |
