[Summary] [Object] To suppress light toward lateral directions from leaking in an illumination device using an EL element for a light source. [Means for Settlement] An illumination device 1 is provided with a light source part 3 that has a planar light emitting panel 2. The light source part 3 is provided with: a cover 5 that is provided on a light emitting surface side of the light emitting panel 2, allows light to exit, and has translucency; and a case 6 that is provided on a non-light emitting surface side of the light emitting panel 2 and retains the cover 5. The cover 5 has: a light exit surface 5a that allows light from the light emitting panel 2 to exit; and a side wall 5b that covers an outer peripheral surface 2a of the light emitting panel 2. The case 6 has: a concave main surface 6a; and a side wall 6b that covers an outer periphery of the side wall 5b of the cover 5. The cover 5 is pushed into the case 6, and side surfaces of the cover 5 are covered by the case 6, so that the light from the light emitting panel 2 is unlikely to exit from the side surfaces of the cover 5, and therefore the light toward lateral directions of the light source part 3 can be suppressed from leaking. |
