PURPOSE:To enhance oxidation resistance of metal powder so as to secure sufficient conductivity and solderability by galvanizing a noble metal on alloyed metal powder. CONSTITUTION:Cu-Ni alloy or Cu-Zn alloy powder coated with one kind of metal selected from a group of Au, Pt, Pd, Ru and Ag is used as metal powder of conductive paste consisting mainly of metallic powder, glass frit and organic vehicle. The reason for the use of Cu-Ni ro Cu-Zn as the alloyed metal is higher oxidation resistance of alloy by itself than Cu, conductivity within an allowable range, and excellent migration resistance and galvanizing property. The conductor being excellent in stability and solderability is therefore attainable. |
