PROBLEM TO BE SOLVED: To easily judge a number of a reheating frequency, and to prevent inconvenience by being excessively reheated by adding a reheating frequency by gas heating power at heat reserving time, and always making a display corresponding to the frequency. SOLUTION: After completing rice cooking, ordinary heat reserving and long-four heat reserving can be selected, and in either case, reheating operation is performed by temporarily burning a gas burner 2 at heat reserving time. At this heat reserving time, when operation is set to the long-four heat reserving in a controller C, a timer is turned on to perform heat reserving control controlled to a temperature lower than an ordinary heat reserving case, and a memory value I is set to 0. When judged that the timer times up, ignition operation to the gas burner 2 is performed, and when the detecting part 3 detects a flame in a prescribed time, reheating control is performed. At this time, the memory value I is rewritten to I+1, and the value I+1 is displayed on the display part 41 of an operation panel 4 as a reheating frequency.
