PROBLEM TO BE SOLVED: To prolong the life in the high temperature by increasing oxidation resistance of a heating body. SOLUTION: The heating body 1 for induction heating device is provided in the passage that is formed of a non-induction heating body so as to pass the liquid and is heated by induction heating and heats the liquid that is supplied so as to pass the above passage. The heating body comprises through holes 2a, 2b, 2c... in which the liquid passes and all the surface of the heating body including the surface of the through holes are coated by an oxidation resistance material. The oxidation resistance material is an oxide that is generated by coating glass on the surface of the heating body. The coated oxidation resistance material is a compound of TiN, TiC, CrN, Al2 O3 , SiC or the like that are coated by PVD(physical vapor deposition) or CVD(chemical vapor deposition) or ceramics.
