To effectively irradiate a display object housed inside without forming a shadow by irradiating a top plate with illumination light originated from a light source incorporated in a base along the inner surface of a side face plate and irradiating the display object below by a reflection surface provided on a part or the entire part of the top plate.

A display part 2 is formed on the base 1 for mounting the display object P by surrounding a periphery by a light transmissive side face plate 3 and providing a light non-transmissive top plate 4 on an upper end, the top plate 4 is irradiated with the illumination light R originated from the light source 6 incorporated in the base 1 along the inner surface of the side face plate 3 and the display object P below is irradiated by the reflection surface 7 provided on the top plate 4. That is, the light source 6 composed of a halogen lamp is installed inside the base 1 and the light R generated from there is guided to an irradiation port 5 by a light guide 8. Then, the reflection surface 7 is irradiated with a part of the light R from the irradiation port 5 along the side face plate 3 while the display object P is irradiated from a lower part and the display object P is irradiated from an upper part.
