A package includes a base body having a mounting portion for mounting a light-emitting device, a frame-shaped first reflection member attached to the upper surface of the base body, an inner peripheral surface of which is shaped into a first light reflecting surface and surrounds the mounting portion, and a frame-shaped second reflection member attached to the upper surface of the base body, with a spacing secured between an inner peripheral surface of the second reflection member and an outer peripheral surface of the first reflection member, the inner peripheral surface surrounding the first reflection member and having a second light reflecting surface at a location above an upper end of the first reflection member.

Package for light-emitting device, light-emitting apparatus, and illuminating apparatus

A light-emitting apparatus with improved dissipation efficiency of heat transmitted to a specific electrode of a light-emitting device is provided. A light-emitting device mounting substrate used for the light emitting apparatus include a base body () which mounts thereon a light-emitting device (); a first electrically conductive path (L) formed within the base body (), one end thereof being electrically connected to a first electrode () of the light-emitting device () and the other end thereof being led out to a surface of the base body (); and a second electrically conductive path (L) formed in the base body (), one end thereof being electrically connected to a second electrode () of the light-emitting device (), and the other end thereof being formed on the surface of the base body (). The first electrically conductive path (L) is made smaller in thermal resistance than the second electrically conductive path (L).
