Further, the upper surface of the heating chamber 12 is opened,
As shown in FIG. 3, an infrared detection device 16 is provided above this opening, and this detection device 16 detects infrared rays emitted from the food to be cooked 15 as it is heated. Then, the output of the detection device 16 is extracted via an amplifier 23. Furthermore, a chopper is provided in the aperture portion to interrupt the incidence of infrared rays on the detection device 16. On the other hand, an operation panel is mounted on the front side of the cliff body 11 located on the side of the door 13, and this operation panel includes a power lamp 17, a cooking lamp 18, a temperature display 19, selection switches 20a, 20b, 20c, A timer 21, a correction lever 22, etc. are provided.
