ABSTRACT:
Conductive metal powders having high conductivity with minimized silver migration are characterized in that an average composition is represented by Ag.sub.x M.sub.1-x (wherein M is at least one metal selected from Ni, Co, Cu and Fe; 0.01.ltoreq.x.ltoreq.0.4) and has a region wherein a silver concentration progressively increases on moving from the inner part toward the surface. The conductive metal powders, which are useful as leads, electrodes and shielding from electromagnetic interference are prepared by solidifying rapidly a molten metal having the specific composition.
