Abstract
A printed wiring board includes a Cu wiring pattern formed on a substrate. A first metal layer is formed on the Cu wiring pattern. A second metal layer is formed on the first metal layer. The first metal layer has a less reactivity with Cu than the second metal layer. The first metal layer and the second metal layer together cause an eutectic reaction.
