A superheated steam generator, capable of generating superheated steam which exceeds about 400° C. even if a litz wire is adopted as an induction heating coil, is generally described. The generator may include induction heating elements that can generate heat by electromagnetic induction and that are housed in a heat-resistant container. The generator may also include a hose that allows cooling water to pass therethrough and which is wound around an outer peripheral surface of the heat-resistant container. A water supply unit for the cooling water is connected to one end of the hose, and the other end of the hose is connected to a steam inlet of the heat-resistant container. An induction heating coil is mounted on an outer peripheral surface of the hose, and a high-frequency power supply unit is connected to the induction heating coil.
