Abstract
A plurality of LEDs (light emitting diodes) are mounted upon a metallic plate member, and thus heat from the plurality of LEDs is transmitted to the metallic plate member. The plate member functions as a heat radiating plate. In addition, a light guide is fixed to the plate member so that a surface of the light guide and a surface of the plate member that face each other are parallel.
