Abstract:
A multilayer wiring board, comprising:a first wiring layer having a first wiring pattern having conductors extending principally in a first direction; a second wiring layer having a second wiring pattern having conductors extending principally in a second direction; the first wiring direction of said first wiring pattern and the second wiring direction of said second wiring pattern being substantially perpendicular to each other, said first wiring layer and said second wiring layer being laminated; and power or ground connections formed of conductive patterns and vias in via holes and extending through said first and second wiring layers, said power or ground connections comprising: a plurality of conductive patterns formed on each of said first and second wiring layers in such a way that each of the long sides is oriented substantially in the same direction of said wiring pattern formed on each wiring layer, respectively, each of said conductive patterns in alignment with a plurality of said via holes, each of said conductive patterns having a nearly rectangular form.
