To provide an induction heating device capable of properly displaying an operation state.
This induction heating device recognizes states of a series resonance impedance and a series resonance frequency of a matching circuit part by a control means. The control means displays a coordinate plane area 556 in a display area 411A of a display means, and displays any one of message buttons 557A-557I at a position including coordinates corresponding to the states of the series resonance impedance and the series resonance frequency of the matching circuit part on the coordinate plane area 556. Thereby, the states of the series resonance impedance and the series resonance frequency of the matching circuit part can be represented by the position of one of the message buttons 557A-557I; the operation state in induction heating can easily be recognized as compared with a structure where the respective states are displayed with two numerical values; and the operation state can properly be displayed.
