<p>A printed circuit board includes a plurality of wiring layers and a plurality of differential signal vias to establish connections between the plurality of wiring layers through via pairs and to be disposed so that paired-vias possessed by a specified differential signal via for transmitting a differential signal different from a signal of another differential signal via adjacent thereto are arranged on a locus of a point distanced equally from each of the paired-vias possessed by another differential signal via.</p> |
