いた油汚れは拭き取る事がし難いという問題があった。However, even with the conventional smooth top plate described above, the surface temperature of the top plate is 200.degree.
There is a problem in that oil stains stick to the peripheral portion above the induction heating means, which has a high temperature in the range of 350 ° C., and the sticky oil stains are difficult to wipe off.

雑となり問題があった。However, since the method of forming the antifouling layer that has been already proposed is usually performed by means such as a flow coater, a roll coater, a spin coater, or dipping, the antifouling layer is formed on the entire top surface of the top plate. Therefore, after the antifouling layer is formed, a part of the antifouling film formed on the surface of the top plate is purposely removed to integrate the top frame for fixing the top plate to the main body with the top plate. However, there is a problem in that the manufacturing process is complicated.
