This induction heating cooker: drives an inverter circuit (23) in accordance with the determination result of a load determining means; calculates, with the drive frequency of the inverter circuit (23) fixed, the change per prescribed time of a value which is based on a primary voltage value dependent on the AC voltage from an AC power source (21) or the DC voltage of a DC power source circuit (22), and based on the current value of the input current to the inverter circuit (23) and/or the coil current flowing to a heating coil (11a); and detects the change in temperature of an object (5) to be heated on the basis of said change per prescribed time. |
