<p><P>PROBLEM TO BE SOLVED: To provide a glass top plate for a heating cooker capable of sufficiently concealing structures inside the cooker even with a color of high brightness, enabling it to hardly discriminate a translucent part from a cooking face of the cooker when a light source is in non-luminous state, and enabling it to visually confirm the translucent part by emission of the light source when it is in a luminous state. <P>SOLUTION: The glass top plate for a heating cooker is provided with a substrate 2 made of translucent and low-expansion glass ceramics, a pearl-tone layer 3 formed on a rear side surface 22 that is an opposite side surface of the cooking face 21 on the substrate 2, a covering layer 4 formed on the pearl-tone layer 3, a shading part 6 composed of a protective layer 61 made of resin containing inorganic pigments arranged on the covering layer 4, and the transparent part 5 composed of a transparent resin layer 51 made of transparent resin arranged on the covering layer 4. It is so structured that the translucent part 5 transmits light from the light source 81 arranged under the glass top plate 1, and the shading part 6 shields the light from the light source 81. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
