The first turn is positioned in an opening of the second turn, and the second turn is positioned in an opening of the third turn. Each of the first and second turns has an opening width larger in a first direction than in a second direction. The first distance between the first and second turns in the second direction is smaller than the second distance between the second and third turns in the second direction. The third distance between the first and second turns in the first direction is smaller than the first distance. The fourth distance between the second and third turns in the first direction is smaller than the second distance. The third turn has an opening width larger in the second direction than in the first direction.
