<p>PROBLEM TO BE SOLVED: To provide an induction heating coil, capable of suppressing heating value of the core, and having superior durability and high performance. SOLUTION: This induction heating coil is equipped with the core, having an internal cooling plate and an external cooling plate and with winding, and an objective face facing opposite to a material to be heated is set on the core. The coil is characterized, by placing the end face on the side of the material to be heated of the external cooling plate on a position retreated from the objective face, or by forming an inclined face on a laminate on the external cooling plate side, or by placing the end face on the side to be heated of the winding on a position which match with the end face on the side to be heated of the external cooling plate on the retreated position, or at a position further retreated from the agreeing position, or by forming the inclined face by laminating steel plates forming the inclined face in the laminating direction of other steel plates forming the core and in the orthogonally intersecting direction with the object face, or by applying a formation obtained by combining these means properly.</p> |
