PROBLEM TO BE SOLVED: To provide a high-frequency induction heating device capable of reducing a power cost for a production process by suppressing radiative heat dissipation to a surrounding object or convective heat dissipation to ambient air.SOLUTION: A reflection member, which has a reflectance of 70% or more with respect to an electromagnetic wave in an infrared wavelength region and which is made of a nonmetal material or a metal material having a plate thickness set thin with respect to current penetration depth, is arranged around a heated member subjected to induction heating. Thus, an energy loss caused by heat dissipation to the environment can be suppressed without a loss of energy charged into the heated member from an induction heating device. Consequently, a power cost for the high-frequency induction heating device can be reduced. |
