A microwave oven includes radiation detecting means for detecting radiations from at least two detection points within a heating oven of the microwave oven. A signal of the radiation detecting means derived from that point of said at least two detection points which is at relatively high temperature is used to control a high frequency wave generator which feeds a high frequency wave into the heating cavity. The radiation detecting means includes a radiation detector and a chopper which chops radiations directed to the radiation detector from said at least two detecting points. |
