Abstract
This invention provides a heating and cooking apparatus in which foods can be accommodated in a heating chamber with good maneuverability and an appropriate finish can be obtained. A temperature detector detects infrared radiation through an opening provided on a wall surface opposed to an opening part for taking in and out foods of a heating chamber. The temperature detector detects the temperature of a plurality of parts on a sealing having the substantially same electric wave penetrability as that of the bottom surface of the heating chamber. Accordingly, even when two foods are arranged right and left irrespective of the size of the foods, the temperature of both the foods can be detected. Then, the user does not needs to extend a hand to the interior of the heating chamber and arrange the foods in front and back positions.
