Abstract
A communication line is disclosed which is able to reduce the difference in the signal propagation time between the wires of the twisted pair. A communication line of the present invention is achieved by cutting and exchanging a pair of wires at the middle point or plural points in the line, so that the positive connecting parts and the negative connecting parts formed by the above cutting and exchanging are equal in length.
