    Abstract: Signal transmission structures within a printed circuit are formed to have reduced loss by making specific accommodations to reduce the surface roughness of an adjacent power plane (14), and thereby reducing the effects of magnetically induced currents. The power plane structure will retain sufficient surface roughness to accommodate manufacturing operations, while also contributing to reduced signal transmission losses in the adjacent signal transmission structure (20, 30). The transmission structures thereby being capable of more efficiently transmitting high speed signals without undesired attenuation and loss.

    Abstract: 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.

    Abstract: A flexible cable is provided in which a transmission characteristic can be ensured in a high frequency band, and electromagnetic noises can be suppressed. A flexible cable 11 includes a sheet-like base member (dielectric substance) 1; an adhesive (dielectric substance) 2 which bonds the base member 1 to a cover member (dielectric substance) 3; a shield member 4 which covers the cover member 3 and is bonded or printed to the cover member 3 to suppress electromagnetic noises to be radiated; and a top coating member 5 which covers the shield member 4 to protect the shield member 4. The flexible cable 11 has a differential signal wire group 7 including differential signal wires 6 through which differential signals pass and guard ground wires 9a which prevent the interference from other differential signals; a low-speed signal wire 8 through which a low-speed signal passes; a ground wire 9 used as a ground; and a shield ground wire 10 which is adapted to allow the electric potential of the shield member 4 to be identical to the electric potential of the ground, all of which are provided in the adhesive 2. The differential signal wires 6 are not covered with the shield member 4.
