Abstract
A differential transmission circuit includes a pair of transmission line conductors and a ground conductor layer, wherein the pair of transmission line conductors include a first straight line region where both the pair of transmission line conductors extend in parallel to each other in a first direction with a first width in a first layer, a first cross region where one of the pair of transmission line conductors is formed in the first layer, the other thereof is formed in a second layer, and the pair of transmission line conductors cross the each other in a three-dimensional manner, the first cross region being disposed on the front side of the first straight line region, and wherein each of the widths of the pair of transmission line conductors in the first cross region is smaller than the first width.
