<P>PROBLEM TO BE SOLVED: To prevent water from being ejected from an ejection nozzle, to reliably secure a flow passage through which steam passes even if scales are deposited in a boiler, and to prevent boiler water from running up. <P>SOLUTION: A heating cooker includes a heating chamber 28 for accommodating food 100, and a boiler 43 which supplies steam generated by heating water to the heating chamber 28. The boiler 43 includes a heat generating unit 43c for heating the boiler 43, a heating surface 43h which is heated by the heat generating unit 43c to heat water into steam, a water feed port 104 having a water feed outlet 104a which feeds water to the boiler 43 and ejects water to the heating surface 43h, and an ejection port 44 for ejecting steam generated by the heating surface 43h from the boiler 43. Surface roughening treatment is applied on the heating surface 43h. <P>COPYRIGHT: (C)2013,JPO&INPIT |
