摘要：
A laminated coil-forming method for winding wires and insulation films around a core, includes the steps of winding a first insulation film around an inner coil formed around the core, winding a second insulation film around the first insulation film with the second insulation film having a smaller width than a width of the first insulation film, and winding a third insulation film around the second insulation film with the third insulation film having a greater width than the width of the second insulation film before forming an outer coil.
