Afterwards, it is judged that whether the heat switch of preservation mode K of the end in mode setting part 5 is pressed (step S24). If this switch is not pressed, then return step S22 (step S24's is no). On the other hand, if end is heated, the switch of preservation mode K is pressed, then the preservation mode K that heats terminates (step S24 is).

It addition, in step S22, when judging cooking bottom temperature �� more than �� 1 (step S22's is no), determine whether that whether cooking bottom temperature �� is more than temperature �� 2 (step S25). This �� 2 is set to the temperature (�� 2 > �� 1) higher than �� 1. And, when cooking bottom temperature �� is bigger than �� 2 (step S25 is), it is judged that too high for temperature, heating part 4 stops (step S26). So, control portion 21 judges the stopping of heating part 4 based on the cooking bottom temperature �� of the pot shape container 3 utilizing vessel temp test section 12 to detect. Afterwards, step S24 is entered. It addition, when when cooking bottom temperature �� is �� less than 2, (step S25's is no), i.e. cooking bottom temperature �� meet �� 1 < �ȡܦ� 2, it is judged that for being just properly carried out preservation of heating, and enter step S24.
