Title: Steam cooker

Abstract: After a preheating operation is performed to raise an inner temperature of a heating chamber to a target preheating temperature (first specified temperature) by a first steam superheater of a steam temperature-raising device, a cooking operation is performed to raise, by the first steam superheater of the temperature-raising device, a temperature of steam obtained by heating of water in a steam generator by heaters 42A, 42B of the steam generator and then supply the steam to the heating chamber. In this process, when inner temperature of the heating chamber detected by an inner temperature sensor 81 during the preheating operation has come to or beyond a steam generation start temperature (second specified temperature) which is lower than a target preheating temperature, a control unit 80 decides that a steam generation start condition has been satisfied, and heats water in the steam generator by the heaters of the steam generator.
