Abstract: A silver-coated copper alloy powder, which has a low volume resistivity and excellent storage stability (reliability), is produced by coating a copper alloy powder, which has a chemical composition comprising 1 to 50 wt % of at least one of nickel and zinc and the balance being copper and unavoidable impurities (preferably a copper alloy powder wherein a particle diameter (D50 diameter) corresponding to 50% of accumulation in cumulative distribution of the copper alloy powder, which is measured by a laser diffraction particle size analyzer, is 0.1 to 15 ?m), with 7 to 50 wt % of a silver containing layer, preferably a layer of silver or an silver compound.

Abstract: When a substrate having a low heat resistance is used, heat treatment at approximately 120° C. at which deformation does not occur is desirable. When a low resistance is achieved regardless of the type of resin used for a conductive paste, a flexible design of a paste is possible according to purposes, and fields to which the paste could be applied are expanded. Thus, a conductive paste capable of forming a conductive film exhibiting a high conductivity even at low temperatures of approximately 120° C. regardless of whether the constituting resin is a thermosetting resin or a thermoplastic resin is provided. In a method for forming a conductive film, a conductive paste in which a dicarboxylic acid having 2 to 8 carbon atoms is added to a paste including silver nanoparticles coated with an organic substance having 2 to 6 carbon atoms, a dispersion medium, and a resin is used.
