PROBLEM TO BE SOLVED: To improve heating performance by winding a coil by the number of turns for sufficient performance when the coil is manufactured having a limited external diameter.SOLUTION: An induction heating coil includes a coil conductor 14, a coil base 12 supporting the coil conductor 14, and ferrite 15 located below the coil conductor 14. The coil base 12 has a plurality of concentric projection parts 13, which have a partial cut part 17. The coil conductor 14 is fitted between the projection parts 13 and shifts to between other projection parts 13 at the cut part 17. |
