The invention provides a winding method of a coil tapping area, and a transformer, and belongs to the technical field of transformer manufacturing. The winding method of the coil tapping area comprises a step of winding a first tapping sub-section or a step of winding a second tapping sub-section, wherein the step of winding the first tapping sub-section comprises: winding, connecting a first tangled positive cake and a first tangled negative cake, and leading out three tapping conducting wires, and the step of winding the second tapping sub-section comprises the steps of winding, connecting asecond entangled positive cake and a second entangled negative cake, and leading out the other three tapping conducting wires. According to the winding method of the coil tapping area and the transformer, the technical problem that an existing coil tapping line can only be led out from the outer diameter side can be solved, and the solution that the tapping line is led out from the inner diameterside is given. 本发明提供了一种线圈
