A tray-shaped box body has, for example, a square bottom surface, an open upper surface, a light-reflecting member provided on an inner surface thereof, side walls inclined outward, and holes formed at least at two positions of the side walls near the bottom surface of the box body. LEDs are provided outside the holes, so as to emit light to an inner space of the box body. Protruding portions are formed at upper sides of the holes formed at the side walls of the box body, so as to extend from the side walls. |
