PROBLEM TO BE SOLVED: To prevent abnormal heating in automatic heat cooking. SOLUTION: In Step S11, whether the temperature Tt after t seconds in a chamber is constant Th (for example, 50 deg.C) or higher is determined. If the temperature Tt is less than a constant Th, whether the voltage V of a temperature sensor has increased byΔV or higher from initial voltage Vo is determined in Step S12. When it reachesΔV, it is regarded as the detection of finishing, and heat cooking finishes in Step S13. If the temperature Tt in the chamber is the constant Th or higher in Step S11, whether the rate of temperature rising dTt/dt after t seconds exceeds a constantα(for example, 0.2 deg.C/second) is also determined in Step S14. When the rate of temperature rising exceeds the constantα, cooking finishes in Step S13.
