PROBLEM TO BE SOLVED: To reduce high frequency loss. SOLUTION: Bonding paint is applied to the surface of each straight-angle wireα1 whose long side of the rectangular cross section is substantially horizontal, using an applicator roll 3a. The position of each straight-angle wireα1 after the paint application is corrected so that its long side of the rectangular cross section is substantially vertical. Each straight-angle wireα1 is then inserted through a vertical slit tool 4 having a slit S that is elongate in the vertical direction and laminated. A bundle of straight-angle wiresα4 after the lamination is inserted through a gap M that is elongate in the vertical direction and provided on a shaping tool 5 by carving and the whole sectional form is adjusted. Accordingly, it becomes possible to suitably produce a heating coil for electromagnetic cooking device that allows heating of cooking devices made of aluminum, copper, or the like. Also as the paint application section and the slit for lamination can be placed closely to each other, which enables miniaturization of the entire device.
