An induction-heating cooker comprising: a top plate adapted to place a cooking container thereon; an inverter circuit disposed below the top plate and having a heating coil to heat the cooking container; and an output setting portion operable to select one of a plurality of different power set values, characterized in that the induction-heating cooker further comprises: an infrared sensor disposed below the top plate to detect infrared rays that are emitted from a bottom surface of the cooking container and pass through the top plate, the infrared sensor outputting infrared detection information corresponding to a temperature of the bottom surface of the cooking container; a scorching detecting portion operable to detect scorching, in which a material to be cooked has burnt and stuck to the bottom surface of the cooking container, based on the infrared detection information, the scorching detecting portion outputting scorching detection information; a controller operable to supply the heating coil with a high-frequency current and control a heating operation of the inverter circuit such that a heating power becomes a power set value selected, the controller comprising: a first time measuring portion operable to measure a cooking time from the start of heating by the inverter circuit; and a loading detecting portion operable to detect addition of a load to the cooking container based on the infrared detection information outputted from the infrared sensor; wherein if the cooking time measured by the first time measuring portion does not reach a first set time, the heating operation is continued even if the scorching detecting portion outputs the scorching detection information, and when the loading detecting portion detects that the load has been added, the cooking time measured by the first time measuring portion is reset and measurement thereof is restarted. a top plate adapted to place a cooking container thereon;
