Abstract
A first coiland a second coilare faced each other across a conductor plate S so that the first coil () and the second coil () become substantially the same in position in a Y-axis direction. The conductor plate S is inductively heated by applying alternating currents at a frequency at which a depth of penetration of the current becomes equal to or less than half a plate thickness of the conductor plate S to the first coil () and the second coil () in opposite directions.
