Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an illumination apparatus capable of suppressing damage, deformations, and the like even if a light source and the incident surface of a light guide plate are positioned with respect to each other with high accuracy.SOLUTION: Even if a light guide plate 1 expands by a temperature change or a humidity change, a distance between an incident surface 13 and a substrate 21, that is, an LED 2 is made constant by compressive deformation of rubber 16. Therefore, it is possible to ensure stable illumination characteristics without damaging or deforming the LED 2 or the light guide plate 1.
