Abstract
A printed wiring board having an interlayer insulation layer and conductive circuits formed on the interlayer insulation layer. The conductive circuits include a first conductive circuit and a second conductive circuit positioned adjacent to each other, and the first and second conductive circuits satisfy a formula, 0.10 T≦|W−W|≦0.73 T, where Wrepresents an upper conductive circuit space between the first and second conductive circuits, Wrepresents a lower conductive circuit space between the first and second conductive circuits, and T represents a thickness of the first and second conductive circuits.
