PROBLEM TO BE SOLVED: To provide a package for storing a light emitting element, which can radiate the light emitted by the light emitting element to outside equally and efficiently, and its manufacturing method. SOLUTION: In a package for storing a light emitting element, where a ceramic sash 2 having a through hole 2a for storing the light emitting element 3 is stacked on the topside of a roughly plate-shaped ceramic substrate 1 having a mount 1a for mounting the light emitting element 3 at the top, the inwall of the through hole 2a of the ceramic sash 2 widens outward at an angle of 55-70 deg. to the topside of the ceramic substrate 1, and also the surface is covered with a metallic layer 1-3 μm in average roughness at the center line and 80% or over in reflectance to the light emitted by the light emitting element. |
