Claim of US Patent No. 10,117,293

1. A transverse flux induction heating device which inductively heats a conductive sheet by allowing an alternating magnetic field to intersect a sheet face of the conductive sheet, the conductive sheet being conveyed in one direction, the transverse flux induction heating device comprising:a heating coil disposed such that a coil face faces the sheet face of the conductive sheet;
a core around which the heating coil is coiled;
a shielding plate formed of a conductor and disposed between the core and a side end portion of the conductive sheet in a direction perpendicular to a conveyance direction of the conductive sheet, the shielding plate facing the side end portion of the conductive sheet; and
a non-conductive soft magnetic material which is attached to the shielding plate,
wherein the shielding plate is interposed between the core and the non-conductive soft magnetic material,
a first depressed portion and a second depressed portion, which face the side end portion of the conductive sheet in the direction perpendicular to the conveyance direction of the conductive sheet are formed in a surface of the shielding plate, the surface facing the conductive sheet, the first depressed portion and the second depressed portion being horizontal to each other, and
the non-conductive soft magnetic material is housed in each of the first depressed portion and the second depressed portion.
