description PROBLEM TO BE SOLVED: To provide oxidation resistant nickel-coated copper powder for electrically conductive paste for forming an electrically conductive wiring part for an electronic circuit, and to provide a method for producing the same. SOLUTION: The nickel-coated copper powder contains nickel-coated copper grains obtained by using copper grains as a core material, sticking a catalyst for plating to the surface of each copper grain by reduction reaction, and applying electroless nickel plating to the outermost surface. In the reduction reaction, hydrazine is used as a reducing agent. COPYRIGHT: (C)2006,JPO&NCIPI
