Abstract
The present invention provides an illumination apparatus that can suppress heat generation during use. The illumination apparatus includes a planar light emitting panel and a heat-radiating mounting member. The mounting member mounts the planar light emitting panel and has a body plate-section. The body plate-section has a through hole for feeding power that penetrates the body plate-section in a thickness direction, and a smooth region substantially free of protrusions. The panel has a panel body and a connecting wiring section. The connecting wiring section electrically connects the panel body to an external power source, and extends through the through hole. The panel has a front surface including a light emitting region that emits light, and a back surface on which another smooth region is provided. The smooth regions are in surface contact with each other over not less than 50% of an area of the light emitting region.
