PURPOSE: An inductive heating cooking device is provided to prevent a damage of a switch device by changing an output according a size of a diameter of a heating vessel. CONSTITUTION: An inductive heating cooking device comprises an inverter portion(30) and a power factor controller(400). The power factor controller(400) comprises a power drive(410), a frequency generator(420), the first current detector(430), the second current detector(450), and the controller(440). The power drive(410) switches alternately the first and the second switch(S1,S2). The frequency generator(420) generates a switching frequency. The first current detector(430) measures a consumed power of an input power. The second current detector(450) measures a current of the second damping diode(D2). The controller(440) controls an output of the frequency.
