- the twist line has been proposed. As shown in FIGS. 7A and 7B, the twisted wire Wt is generally manufactured by twisting a plurality of (two in this example) electric wires W1 and W2.
- one conventional twisted wire manufacturing device forms a wire pair by arranging two wires before being twisted substantially in parallel, and makes one end of the wire pair unrotatable.
- the twisted wire is manufactured by fixing and rotating the other end around the axis of the electric wire pair (see, for example, Patent Document 1 and Patent Document 2).
