<p><P>PROBLEM TO BE SOLVED: To prevent the external appearance of a top plate from looking poor. <P>SOLUTION: A heat resistant layer 412 coated with inorganic paint is provided on the back side of a top plate body 41 formed of crystallized glass, and a protective layer 413 coated with organic paint is provided on the heat resistant layer 412. Thereby, transmission of built-in components are prevented by heightening covering power. In addition, the protective layer 413 is coated with the organic paint except for a portion corresponding to an electromagnetic induction heater 321, and thereby even when a metallic pan 7 on the top plate 40 is abnormally heated, there is no chance that the temperature of the organic paint forming the protective layer 413 exceeds the limit of its heat resistant temperature and discolors. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
