INDUCTION HEATING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an induction heating device enabling heat-treatment of an optimum temperature profile suitable for heat-treatment of a body to be heated by realizing heat uniformity in a high temperature range of 1000°C. SOLUTION: In an induction heating body provided facing an induction coil provided along a plane in a concentric circle shape or a spiral shape, the distance of a central part corresponding to a central position of the concentric circle shape or the spiral shape of the induction coil from a coil surface in which a current path of the induction coil is provided is shorter than a peripheral part located in the periphery of the central part.
