A light-emitting element storing package which ensures the efficient reflection of light emitted by a light-emitting element by a reflector frame and thereby improves the brightness of the emitted light, and a method of manufacturing the same are provided. In a light-emitting element storing package includes: an insulating substrate consisting of a ceramic board, a reflector frame composed of a ceramic material, joined to the upper surface of the substrate along its outer edge and having an inner wall surface defining a light-reflecting surface, and a wiring pattern layer formed on the upper surface of the substrate for connection with a light-emitting element, a light-emitting element storing concave portion, which is defined by the substrate and the reflector frame, and in which the light-emitting element is mounted on the wiring pattern layer, the reflector frame is mainly composed of nitride ceramics and its light-reflecting surface is composed of white ceramics.
