は、引き出し線3が重ならないように配置する。In the present embodiment, the winding groove 5 is provided with a rib 4 for leading out the lead 3 of the coil 2. In FIG. 1, the ribs 4 are uneven in the vertical direction toward the drawing, and each of the leads 3 is hooked on the ribs 4 by using the unevenness. The positions of the ribs 4 are arranged so that the lead lines 3 do not overlap.
