Abstract
In the present invention, generation of occurrence of a wiring area is prevented, and a reflection by an inconsistency of a characteristic impedance of a high-speed signal line and a through hole connecting portion. By doing so, a conductor pattern of a raised shape is formed on each of front and back of a through hole, on a GND layer closest to the high-speed signal line in the vicinity of the connecting portion of the high-speed signal line and the through hole. Further, the conductor pattern is a trapezoidal shape, and is a shape which becomes wider as it becomes closer to the through hole.
