Abstract: There is provided a soldered article comprising a component having a Cu conductor joined with a solder, wherein the solder comprises about 0.1 to 2.0% by weight of Cu, about 1.0 to 7.5% by weight of Bi, and the balance being Sn. By using the above described lead-free solder, the occurrence of leaching is suppressed during soldering, and the solderability and joining strength can be improved. Since the solder does not contain Ag, material cost can be reduced, thus enabling reductions in the cost of the entire soldered article.
