A light-emitting panel of the present invention has a LED, a surface light-emitting member, a light source holder, and a holder supporting portion. The surface light-emitting member has a rectangular plate shape and at least one surface of front and back surfaces is surface-emitted by entering light from the light source into an incident edge.
