PROBLEM TO BE SOLVED: To restrain the appearance of a sticky condition due to the excessive local supply of water to a cooked ingredient under the application of a simplified structure and energy saving, and further restrain the amount of dew flowing down to the upper part of a body at the time of opening a cover body. SOLUTION: Insulation heating and rice cooking heating are used with a heating source in common. As a result, a reasonable heating system can be realized. Furthermore, a heating balane between a pot 5 and a cover body 31 in heat insulation process is established so that after cooking rice approximately at 2/5 cooking quantity of maximum cooking capacity, a heat insulation process is implemented without opening a cover body 31, and when the cover body 31 is opened after the lapse of 4 to 8 hours of heat insulation time, the quantity of dew condensed on the internal surface of the cover body 31 flowing down to the upper part of a body 1 for housing the pot 5 is equal to or less than 3 mL and the amount of dew condensation on the internal surface of the pot 5 involving no cooked ingredient is equal to or less than 2 mL.
