  However, in the technique disclosed in Patent Document 1, when the rice cooker is made to perform communication according to a near-field communication standard such as NFC (Near Field Communication) communication, the distance between the wireless communication terminal and the communication substrate is set. There existed a subject that the communication board | substrate had to be arrange | positioned in the vicinity of the external appearance of a rice cooker so that it might adjoin.

  Moreover, in a rice cooker, the operation panel which performs operation of a rice cooker is provided, and the liquid crystal display part may be provided in the vicinity. When performing NFC communication between the wireless communication terminal and the rice cooker, it is desirable to dispose the NFC communication unit in the vicinity of the operation panel and the liquid crystal display unit from the viewpoint of improving user operability. However, if an antenna unit for performing NFC communication is provided on the operation board on which the liquid crystal display element is mounted, the distance from the outer surface to the antenna unit is as much as the thickness of the liquid crystal display element, and the wireless communication terminal is brought closer to the outer surface. However, the communication sensitivity may be low or communication may not be possible. Therefore, the NFC communication substrate has to be provided separately from the substrate on which the liquid crystal display element is mounted. In addition, in order to arrange the NFC communication board separately from the operation board on which the liquid crystal display element is mounted, it is necessary to avoid the liquid crystal display element and the operation board on which the liquid crystal display element is mounted. Or there existed the subject that internal space had to be reduced.
