<p>PROBLEM TO BE SOLVED: To provide an induction heating device capable of detecting a heating object placed above plural heating coils with an inexpensive structure.SOLUTION: An inverter circuit 16 includes: at least a first switching element 44 and a second switching element 45 therein. The inverter circuit 16 controls the power supply by exclusively supplying the power to the first switching element and the second switching element. When the inverter circuit is controlled to supply the power using only a first power supply period in which the ratio of the power supply time of the first switching element or the second switching element with respect to the operation cycle of the first switching element or the second switching element is less than 0.5, the inverter circuit determines whether a heating object is placed above the plural heating coils on the basis of a relation of detection results between current detection means 50aa-50ac and voltage detection means 49aa-49ac.</p> |
