Abstract
Alloy powder which is low in price and is unlikely to be oxidized on the surface, and a dispersion-type conductor using the alloy powder in which electromigration is not likely to occur. Melt of copper and silver is cooled at a high cooling speed of 10.sup.5 .degree. C./s or higher. Alloy powder having a composition expressed by a chemical formula Cu.sub.x Ag.sub.1-x (where 0.80.ltoreq.X.ltoreq.0.99) is obtained. Also, a dispersion-type conductor is produced by dispersing 100 parts by weight of the alloy powder in between 5-100 parts by weight of a binder. Thus, the low-priced alloy powder and the dispersion-type conductor of high quality and high reliability can be obtained.
