A coil device 10 comprises a first bobbin 40 provided with a first winding part 45 at an outer circumference and a second bobbin 50 provided with a second winding part 55 at an outer circumference. A plurality of partition walls 46, separating portions of the wire 22 which are adjacent to each other along the scroll axis Z of the first wire 22 are formed on the first winding part 45 along the scroll axis at predetermined intervals. A section width w1 of each section 47, which is along the scroll axis Z, separated by the partition walls 46 is determined so that only one wire 22 can pass through. A height of the partition walls 46 is determined so that one or more of the wires 22 can pass through. At least one connecting groove 46a, connecting each section which are adjacent to each other, is formed on each partition wall 46. |
