Abstract
A substrate includes a power plane and a ground plane that are placed apart from and are substantially parallel to each other, and at least one signal line that is placed between the power plane and the ground plane. The ground plane includes a first conductive layer having a first conductivity. The power plane includes a second conductive layer having the first conductivity, and the power plane or the ground plane includes a third conductive layer having a second conductivity lower than the first conductivity. The third conductive layer faces the at least one signal line across a dielectric substance.
