A heat generating layer 12b which is a heat generating means provided on the top plate 12, and a power cable 18 which is a power supplying means for supplying power to the heat generating layer 12b.

  The top plate 12 is composed of a single sheet glass 12a, and safety can be enhanced by employing, for example, tempered glass or laminated glass in preparation for an unexpected impact. In this embodiment, the glass sheet 12a has a shape that fits within the internal dimensions of the leg portion 16, but may have a dimension that protrudes outward from the mounting position of the leg portion 16, and its outer shape. The shape is not limited to the rectangular shape shown in the figure, and can take various forms such as a circle, an ellipse, and other polygons. On the plate glass 12a of the top plate 12, a heat generating layer 12b that generates heat when energized is formed over substantially the entire lower surface thereof. The heat generating layer 12b is typically a coating layer of a light-transmitting metal thin film, and can be formed using a metal oxide such as tin, gold, silver, indium, zinc, or titanium. Alternatively, the heat generation layer 12c can be formed using a water-soluble heat generation paint, for example, one described in JP-A-8-41388. The heat generating layer 12b is generally provided on the bottom surface of the top plate 12 as in the present embodiment in order to prevent damage when an object is known on the top plate.
