Abstract
A multilayer interconnection board includes a plurality of laminated ceramic layers. Wiring electrodes are disposed on principal surfaces of the ceramic layers, and dot patterns are arranged around the wiring electrodes. The dot patterns are arranged such that the density distribution thereof is varied such that the ratio of the presence of the dot patterns in the vicinity of the wiring electrode is relatively large and the ratio of the presence is reduced as the distance from the wiring electrode increases.
