This induction heating cooker: drives an inverter circuit (23) in accordance with the determination result of a load determining means; sets the amplification factor of an amplifying means in accordance with the determination result of the load determining means and the detection value of an input current and/or a coil current; calculates the change per prescribed time of the detection value amplified by the amplifying means with the drive frequency of the inverter circuit (23) fixed; and detects the change in temperature of an object to be heated on the basis of said change per prescribed time. |
