Abstract
The object of the present invention is to provide a light-emitting element mounting member and a semiconductor device using the same that is easy to process and that allows adequate heat dissipation. A light-emitting element mounting memberincludes: a substrateincluding an element mounting surfacemounting a semiconductor light-emitting elementand first and second conductive regionsdisposed on the element mounting surfaceand connected to the semiconductor light-emitting elementa reflective memberincluding a reflective surfacedefining an internal spacefor housing the semiconductor light-emitting elementand containing a metal disposed on the element mounting surfaceand a metal layerdisposed on the reflective surfaceThe reflective surfaceis sloped relative to the element mounting surfaceso that a diameter of the internal spaceis greater away from the element mounting surface
