PURPOSE:To make it possible to manufacture heating coils separated with a predetermined gap easily by winding a first heating coil between a pair of plates facing each other, then disposing a plurality of guides on its outer side, and winding a second coil about them. CONSTITUTION:After a first heating coil 11 is wound, a pin fixing member 12 having pins 12a fixed in it is installed in plates 7 facing each other, and a coil is wound around the pins 12a contacting them. Heating coils of a structure having a predetermined space 14 between the coils can thus be manufactured very easily, and need of winding coils with a spacer inserted in the space is eliminated, thereby heating coils of this structure can be manufactured at a low cost. |
