PROBLEM TO BE SOLVED: To provide an induction heating system capable of concentratedly heating corner sections of a heated object and capable of suppressing the power consumption required for heating. SOLUTION: A pair of iron cores 10a, 10c wound with heating coils 12a, 12c are arranged face to face across a heating object 1, another pair of iron cores 10b, 10d wound with heating coils 12b, 12d are arranged face to face across the heated object 1 perpendicularly to the layout of the iron cores 10a, 10c, and the iron cores 10a, 10b, 10c, 10d are magnetically coupled by yokes 11a, 11b, 11c, 11d. This induction heating system is carried current from a high-frequency inverter power supply so that a pair of iron cores 10a, 10c become positive poles and the other pair of iron cores 10b, 10d become negative poles.
