PROBLEM TO BE SOLVED: To provide a rice cooker which can cook tasty rice with fully gelatinized starch by introducing overheated steam with higher temperature than the boiling point of water to apply a necessary and sufficient amount of heat to the rice in the pot while scorching of the rice and desiccation of the rice at a top layer of the pot are prevented. SOLUTION: The rice cooker is so constituted that the pot 2 is heated by a pot heating means 4 and the temperature in the pot 2 is sensed by a pot temperature sensing means 5, an amount of the rice in the pot 2 is judged by an amount of rice judgment means 6, the steam to be supplied to the rice in the pot 2 is generated by a steam generating means 9, the rice in the pot 2 is heated by a cover heating means 25 from a cover 3 which covers the upper surface aperture of the pot 2, wherein at least a part of the cover 3 is heated hot to 100°C or higher by the cover heating means 25, the steam which is generated by the steam generating means 9 is heated by a high-temperature section of 100°C or higher of the shutter 3, and the steam is heated to the boiling point of water or higher to be introduced into the pot 2.
