Patent ID: 7504587

Claim:
A parallel wiring comprising: at least one first differential line including two wiring lines which are substantially parallel to each other in a reference direction; and at least one second differential line including two wiring lines which are substantially parallel to each other in the reference direction, wherein the two wiring lines of the at least one first differential line and the two wiring lines of the at least one second differential line are not twisted, wherein one wiring line of the at least one first differential line and one wiring line of the at least one second differential line adjacent to said one wiring line of the at least one first differential line oppose each other obliquely with respect to the reference direction, the one wiring line of the at least one first differential line and another wiring line of the at least one first differential line being provided obliquely with respect to the reference direction, and wherein the one wiring line and the another wiring line of said at least one first differential line are arranged at positions where a coupling coefficient between the at least one first differential line and said at least one second differential line adjacent to the at least one first differential line is smaller than a specified value determined by a noise margin.
