An induction cooking system, comprising: heat-inputting means setting a heat level from among rough heating levels that can be set to a heating coil configured to heat a heating load by induction; switching means switching the heating level that is set by the heat-inputting means to a corresponding one of heating levels for fine adjustment; characterized in that the induction cooking system further comprises: heat-displaying means including a plurality of display windows that are provided for each of a low heat range, a moderate heat range, and a high heat range, the ranges being defined on the basis of the rough heating levels that can be set to the heating coil; first display-controlling means displaying the plurality of display windows in the heat-displaying means in a predetermined display color, determining that an input mode is for coarse adjustment of heating power when a heating level is inputted from the heat-inputting means, determining a display window for the set heating level, and making display windows from a display window in a lowest heating level in the input mode for coarse adjustment of heating power up to the display window for the set heating level change color; and second display-controlling means determining that the input mode is for fine adjustment of heating power when detecting the switching of the heating level to the corresponding one of the heating levels for fine adjustment performed by the switching means, determining heating level of the fine adjustment in the range in which a display window that had been lastly brightened up by the first display-controlling means, determining a display window for the determined heating level for the fine adjustment that is the same as or approximate to the set heating level, and making display windows from a display window in a lowest heating level for fine adjustment in the input mode for fine adjustment of heating power up to the determined display window change color. heat-inputting means setting a heat level from among rough heating levels that can be set to a heating coil configured to heat a heating load by induction; switching means switching the heating level that is set by the heat-inputting means to a corresponding one of heating levels for fine adjustment; heat-displaying means including a plurality of display windows that are provided for each of a low heat range, a moderate heat range, and a high heat range, the ranges being defined on the basis of the rough heating levels that can be set to the heating coil; first display-controlling means displaying the plurality of display windows in the heat-displaying means in a predetermined display color, determining that an input mode is for coarse adjustment of heating power when a heating level is inputted from the heat-inputting means, determining a display window for the set heating level, and making display windows from a display window in a lowest heating level in the input mode for coarse adjustment of heating power up to the display window for the set heating level change color; and second display-controlling means determining that the input mode is for fine adjustment of heating power when detecting the switching of the heating level to the corresponding one of the heating levels for fine adjustment performed by the switching means, determining heating level of the fine adjustment in the range in which a display window that had been lastly brightened up by the first display-controlling means, determining a display window for the determined heating level for the fine adjustment that is the same as or approximate to the set heating level, and making display windows from a display window in a lowest heating level for fine adjustment in the input mode for fine adjustment of heating power up to the determined display window change color.
