PROBLEM TO BE SOLVED: To extremely prevent a situation that excess heating and insufficient heating from occurring when a plurality of foods are simultaneously heated and cooked. SOLUTION: When a plurality of foods are simultaneously heated, the temperatures of a plurality of spots are detected by an infrared ray temperature sensor. In each spot, an estimated reach time t0i in which temperature reaches a set temperature Tset is calculated and an average value of estimated reach times is decided as a remaining heating time trA. When the estimate reach time in each spot is within a given range on a basis of a heating time, ((0.4×trA)<=t0i<=1.6×trA) reports and displays that heating is completed when a heating time elapses and heating of all foods is simultaneously completed. In case an estimated reach time is shorter than (0.4×trA), when a corresponding spot is heated for the estimated reach time, heating is stopped once, completion of heating of a part of the foods is reported and displayed. In case the estimated reach time is longer than (1.6×trA), after a lapse of the heating time trA, heating is stopped once, and it is reported and displayed that a food needing additional heating is present.
