    • Provided is a printed circuit board 100 capable of increasing an inductance value of a power pattern and a ground pattern while keeping a low electric resistance value of the power pattern and the ground pattern. The printed circuit board includes a printed wiring board 101 including: a power layer 113 having a power pattern 131 formed therein; and a ground layer 112 having a ground pattern 121 formed therein. On the printed wiring board, an LSI 102 as a semiconductor device and an LSI 104 as a power supply member are mounted. The ground pattern has a first ground region R that overlaps the power pattern as viewed from the direction perpendicular to the surface of the printed wiring board. In the first ground region, at least one defect portion 122 is formed. In the first ground region, the defect portion forms a region 121a that is narrower than the power pattern.
    • 提供了一种印刷电路板100,其能够在保持电源图案和接地图案的低电阻值的同时增加电源图案和接地图案的电感值。 印刷电路板包括印刷线路板101,印刷线路板101包括:功率层113,其具有形成在其中的功率图案131; 以及其中形成有接地图案121的接地层112。 在印刷线路板上安装有作为半导体装置的LSI102和作为电源部件的LSI104。 从垂直于印刷线路板表面的方向来看,接地图案具有与电源图案重叠的第一接地区域R. 在第一接地区域中,形成至少一个缺陷部分122。 在第一接地区域中,缺陷部分形成比功率图案窄的区域121a。
