Abstract
A circuit board comprises a substrate made of a semi-insulating or insulating material, an insulating layer formed on the substrate and having a lower dielectric constant than the dielectric constant of the substrate, and a plurality of wiring conductors formed at predetermined intervals on the insulating layer. The insulating layer has a thickness determined according to the distance between adjacent wiring conductors and equal to 0.5 to 2.5 times the distance noted above, for the purpose of reducing cross-talk noise.
