<p><P>PROBLEM TO BE SOLVED: To provide an induction heating device with a structure capable of properly recognizing a current-carrying state of an induction heating coil. Ž<P>SOLUTION: A hardening device 1 is composed such that multiple induction heating coils 10 are connected in parallel to a high-frequency power supply 2. The induction heating coil 10 has a heat treatment part 31 for heating a treatment object, and a conduction part 32. A parallel part 35 is connected to the conduction part 32, and is structured to be able to detect an induction current flowing to a current detecting coil 38 mounted thereto.
