る。Operation The method for manufacturing an induction heating coil according to the present invention comprises the steps of winding the first heating coil between a pair of opposing plates, and then arranging a predetermined interval in the outer circumferential portion of the first heating coil and its radial direction. The guide is arranged vertically from the outside of the facing plate, and subsequently the second heating coil is wound around the guide so as to be wound, so that a space can be easily provided between the first heating coil and the second heating coil. Can be provided, and the interval between the first heating coil and the second heating coil can be arbitrarily set by changing the position of the guide. When the first heating coil and the second heating coil are fixed to each other, the guide is not removed from the facing plate, and the first heating coil and the second heating coil are attached to the facing plate and the guide with an adhesive or varnish while being attached to the facing plate. Since the heating coil is fixed, it is not necessary to provide the opposing plate with a protrusion or the like for preventing the second heating coil from being unwound and maintaining the distance from the first heating coil. Therefore, when the first heating coil is wound, there is no risk of damaging the insulating coating of the wire with the protrusions, and the interval between the first heating coil and the second heating coil can be formed with high accuracy. it can. Further, the above-mentioned guide can be easily removed after fixing the heating coil winding, the conventionally used spacer is unnecessary, the cost of the heating coil can be reduced, and the labor required for winding can be reduced. It is possible to reduce the number.
