摘要： There is provided an induction heating cooker capable of preventing a pan having a pan bottom warped in a convex shape or a pan having a pan bottom with a small thickness from being excessively heated. The induction heating cooker includes a heating coil (2) operable to perform induction heating of a cooking container, an inverter circuit (7) operable to supply a high-frequency current to the heating coil, an infrared ray sensor (3) operable to detect an infrared ray radiated from the cooking container, an electric power integrating section (81) operable to integrate an amount of heating electric power outputted from the inverter circuit, and a heating control section (82) operable to control the output of the inverter circuit. If an integrated value from the electric power integrating section is less than a predetermined value when an amount of increase in the output of the infrared ray sensor has reached a first predetermined value after a start of heating with a first amount of heating electric power, the induction heating cooker shifts to a first heating control mode. If the integrated value from the electric power integrating section is equal to or more than the predetermined value, the induction heating cooker shifts to a second heating control mode. In the first heating control mode, the amount of heating electric power is reduced to a second amount of heating electric power lower than the first amount of heating electric power. In the second heating control mode, heating is performed with a third amount of heating electric power which is larger than the second amount of heating electric power.
