PROBLEM TO BE SOLVED: To form a shape, in which a winding start terminal and winding end terminal are exposed at the opposite position across a ring by a method, wherein the wire is returned to the start position of winding by way of the central space of the ring at a position only a substantially half-periphery of a ring core, and the remaining half-periphery is wound from the start position of the winding. SOLUTION: Two conductors coated with insulation are arranged adjacent to each other to form a wiring 3 of a paired wire structure, which is wound passing through a central space 2a of a ring ranging over a substantially half- periphery of ring core 2 from a start terminal 3a. When a prescribed turns of winding are wound, the winding 3 is returned to a winding start position near a start terminal 3a by way of the central space 2a of the ring core 2. Next, the wire is wound by only a prescribed turns of winding in the same direction, ranging over the remaining half-periphery of the ring core 2, and an end terminal 3b of the winding 3 is led out to a position nearty opposite to the start end 3a, and the wire 3 is wound substantially over the entire periphery of the ring core 2.
