    • A printed wiring board comprises ground layers stacked via insulator(s); a first through hole; second through holes formed at predetermined positions along a circle concentric with a center axis of the first through hole; clearances provided between the first through hole and each of the ground layers; and signal wirings each extending from the first through hole through the clearance between predetermined ones of the ground layers, disposed between predetermined second through holes of the second through holes. Each of first clearances in the ground layers neighboring layer in which the signal wiring is disposed has an outline that a distance between the first through hole and outline of the first clearance is minimum of the signal wiring. Each of second clearances in the ground layers not adjacent to the signal wiring has an outline formed outside a circle connecting each center of second through holes centering the first signal through hole, such that outline of second clearance docs not contact with the second through holes. The second through holes arc not connected to the ground layers that are not adjacent to the signal wiring but are connected to the ground layer neighboring layer in which the signal wiring is disposed.
    • 印刷电路板包括通过绝缘体堆叠的接地层; 第一个通孔; 沿着与所述第一通孔的中心轴同心的圆的预定位置形成的第二通孔; 间隙设置在第一通孔和每个接地层之间; 以及信号布线,其各自从第一通孔延伸穿过位于第二通孔的预定第二通孔之间的预定接地层之间的间隙。 其中布置信号布线的地层相邻层中的每个第一间隙具有第一通孔之间的距离和第一间隙的轮廓线是信号布线最小的轮廓。 与信号线不相邻的接地层中的每个第二间隙具有形成在围绕第一信号通孔的第二通孔的每个中心的圆周外的轮廓,使得第二间隙的轮廓不与第二通孔接触。 第二通孔不连接到不与信号线相邻的接地层,而是连接到布置信号布线的接地层相邻层。
