Transverse flux induction heating device

A transverse flux induction heating device, comprising:

• a pair of coils having at least one coil arranged on a front side and at least one coil arranged on a rear side of a planned conveyance plane of a conductor sheet to make alternating magnetic fields generated through energization of alternating currents in mutually the same direction intersect the planned conveyance plane of the conductor sheet;
• and
• cores arranged by a set for each coil forming the pair of coils,
• the set of cores arranged for each coil having a plurality of partial cores arranged in a state of having an interval therebetween in a width direction,
• the width direction being a direction perpendicular to a conveyance direction of the conductor sheet and a facing direction of the coils,
• each of the partial cores having a body portion and a center leg portion,
• the body portion being extended in the conveyance direction from a region on an upstream side in the conveyance direction of the coil to a region on a downstream side in the conveyance direction of the coil, on a back side of the coil,
• the back side being an opposite side to a side where the planned conveyance plane exists, and
• the center leg portion being extended in a direction of the planned conveyance plane from the body portion to pass through a hollow portion of the coil, wherein:
• the set of cores has at least one bridge core capable of being magnetically coupled to at least two partial cores out of the partial cores;
• and
• the bridge core is arranged on the back side of the partial cores.
