PROBLEM TO BE SOLVED: To offer an induction heater which can heat uniformly a heating plate even when it is a heating plate with wide width, or with complicated form. SOLUTION: The induction heater 100A comprising a plural of a projection part 11aa-11mn prepared and projected in one of a surface side of a heating plate 10A, a single wire rod 21 for coil wired in a predetermined winding direction for each the two or more projection part 11aa-11mn, and an alternate current power supply 30A which supplies a predetermined high frequency current to the wire rod 21 for coils, transmits an equal quantity of heat to the heating plate 10A by generating an uniform induction heating to each of the projection part 11aa-11mn, by supplying the prescribed high frequency current to the wire rod 21 for coils. |
