Abstract
A printed wiring board includes a first conductive layer, a second conductive layer arranged at a gap with respective to the first conductive layer, a third conductive layer, a first via conductor and a second via conductor, and a third signal wiring pattern. A first signal wiring pattern is arranged on the first conductive layer, a second signal wiring pattern is arranged on the second conductive layer, and a third signal wiring pattern that is arranged on the third conductive layer. The third conductive layer is arranged between the first conductive layer and the second conductive layer via an insulating layer. The first via conductor and the second via conductor, which are arranged to be mutually adjacent, connect the first signal wiring pattern to the second signal wiring pattern. The third signal wiring pattern connects the first via conductor to the second via conductor.
