PROBLEM TO BE SOLVED: To reduce the use amount of a binding line for holding a lower plate and an upper plate in a coil device.SOLUTION: In a coil device 12, a first binding part 26 and a second binding part 28 are arranged in line symmetry. Those first binding part 26 and second binding part 28 comprise: for example, first winding/fastening parts 30 and 36 and second winding/fastening parts 32 and 38 disposed in a lower plate 18; and hooking parts 34 and 40 disposed in an upper plate 20. A first binding line 56 whose winding start end is wound/fastened by the first winding/fastening part 30, and whose winding finish end is wound/fastened by the second winding/fastening part 32 via the first hooking part 34 is extended in the first binding part 26. A portion going from the first winding/fastening part 30 to the hooking part 34 and a portion going from the second winding/fastening part 32 to the hooking part 34 of the first binding line 56 are inclined so as to be expanded like a taper to form inclined parts 60 and 62. In the same way, a second binding line 58 is extended in the second binding part 28. |
