Abstract: A coil winding includes a coil. The coil has a first winding segment and a second winding segment. The first winding segment includes a first lead. The second winding segment includes a second lead. The first winding segment is stacked as a first winding portion, and the first lead is connected with the first winding portion. The second winding segment is arranged along a lateral direction as a second winding portion, further arranged on the second winding portion along a lateral direction as a third winding portion, and further arranged on the third winding portion along a lateral direction as a fourth winding portion, and the second lead is connected with the fourth winding portion. Therefore, the space where the first lead located at is directly and sufficiently used, none of any extra space is occupied, hence the space can be effectively utilized.
