The number of the upper temperature detecting elements 5 equal to the number of the heating parts that can be heated on the plate 1 is provided, and each upper temperature detecting element 5 can observe the object to be heated that is heated by each heating part. The temperature distribution of the entire plate 1 having the heating unit may be observed by providing a plurality of upper temperature detection elements 5, and each having one to several upper temperature detection elements 5 and driving units. The heating unit and the entire plate 1 may be scanned to observe the temperature of the heating unit and the temperature distribution of the entire plate 1.

  Next, communication between the first communication unit and the second communication unit will be described in detail. As described above, the communication may be wired or wireless, and the wireless may be communication using radio waves or infrared rays. The communication may be bi-directionally transceivable. At a minimum, the second communication unit 14 side is constituted by a transmission unit, and the first communication unit 9 side is constituted by a reception unit.

  When the second communication unit 14 side is configured as a transmission unit and the first communication unit 9 side is configured as a reception unit, the temperature detection device 4 always detects the temperature of the heating unit or the entire plate 1 during cooking, and the detected temperature information. Is transmitted from the second communication unit 14, and the first communication unit 9 receives the sent temperature information and sends it to the control unit 7. The control unit 7 is currently cooking based on the sent temperature information. When the temperature information that is not considered normal from the current cooking is received, the energization to the heating coil 2 is stopped and an error is displayed on the display unit. For example, the lower temperature detection element 6 that detects the temperature of the bottom surface of the heating container 11 cannot detect the temperature normally when cooking is performed with the operation unit 10 set at 180 ° C., and temperature information of 300 ° C. is displayed. This is a case where the temperature is detected by the temperature detection device 4.
