PROBLEM TO BE SOLVED: To solve the problem that in a thermal conduction mechanism of a conventional heating cooker, an air layer, or the like, exists due to a separate structure of a vessel and a heating means, so that thermal efficiency goes down. SOLUTION: An electric kettle is composed of a vessel 11 containing a liquid 10, an insulating layer 12 formed on a bottom surface of the vessel 11, and a heating body 13 formed on the insulating layer 12 to heat the liquid 10. According to this structure, since the heating body 13 and the vessel 11 are structured integrally, a thermal efficiency is increased, energy-savings can be achieved, and the size of the kettle can be reduced.
