A frame has an outer frame made of microcellular foam resin, and two inner frames made of the microcellular foam resin. The two inner frames are arranged together inside the outer frame. Both of the inner frames and the outer frame include openings provided at respective upper portions and recess portions formed downwardly from the openings, respectively. An LED light source, which is arranged inside a light guide space, emits light with a light emitting face thereof directing toward the light guide space. Accordingly, light from the LED light source is uniformly emitted from a light extraction portion. Also, an LED light source arranged inside a light guide space emits light directing toward the light guide space. Accordingly, light from the LED light source is uniformly emitted from a light extraction portion.
