Heat antifouling substrate and cooking appliances using the same

PROBLEM TO BE SOLVED: To provide a heat resistant antifouling substrate board made of a chemically adsorbed single molecular membrane of a fluorine compound containing a siloxane bonding and a heat-cooking device using it, the device showing water repellent and oil repellent properties and heat resistance and being produced easily. SOLUTION: The heat resistant antifouling substrate board 1 is composed of a heat resistant substrate board 3 having silicone oxide 2 on its surface and an antifouling thin layer 4 consisting an organic fluorine compound containing a siloxane bonding, which is formed on the surface of the silicone oxide 2, while the silicone oxide 2 is a material containing at least not higher than 13 wt% of an alkaline component selected from an alkaline metal and an alkaline earth metal and at least 1-22 wt% of zirconium and 1-24 wt% of titanium, and thus a heat resistant antifouling substrate board showing water and oil repellent properties and heat resistance can easily be obtained.
