Means for Solving the Problems In order to solve the above problems, a rice cooker of the present invention has an induction coil provided in a bottom portion of a body formed by an outer case and a protection frame, and an alternating coil is provided in the protection frame of the body. A pot that generates heat by a magnetic field is housed therein, opposed to the induction coil via a protective frame, and an upper end peripheral portion of the pot is placed on a shoulder of the container to support the pot in the container. Thereby, a substantially uniform space is formed between the side peripheral portion and the bottom of the pot and the protection frame, and a bottomed cylindrical temperature sensor holding portion is integrally formed at the bottom of the protection frame to hold the temperature detection element. The temperature detector thus formed faces the interior of the space from the temperature detector holder, and is higher than the inner bottom surface of the protective frame in a state of contact with the supported pot.
