<p><P>PROBLEM TO BE SOLVED: To provide an induction heating device capable of heating an object to be heated that is made of a material having a low permeability and a high electrical conductivity, the heating device reducing lift exerted on the object to be heated and causing a low loss. <P>SOLUTION: An electrical conductor 11 is provided between a heating coil 3 and an object 8 to be heated that is made of a material having a low permeability and a high electrical conductivity. The electrical conductor 11 has a lifting-force reducing function to reduce the lifting-force exerted on the object 8 to be heated by a magnetic field produced by the heating coil 3, and includes induction current limiting means 12, 14 and 15 for limiting an induction current generated in the electrical conductor 11 along the direction of a magnetic material 4. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
