PURPOSE:To improve the heating efficiency of an induction heating device. CONSTITUTION:Plates 15, 16 are provided between a heating coil 9 and a material 10 to be heated. The plates are formed of two boards, and a space layer 17 is provided between them. By passing a cooling air to the air layer 17, the heat insulation between the heating coil 9 and the material 10 to be heated is performed to prevent the heat of the material 10 to be heated from being transmitted to the heating coil 9, and the cooling effect is enhanced, whereby the heating efficiency is improved. |
