<P>PROBLEM TO BE SOLVED: To provide a method for easily manufacturing conductive particles in which noble metals are uniformly precipitated without degrading the precipitation rate of the noble metals. <P>SOLUTION: The method for manufacturing conductive particle includes a step of forming a nickel plating layer on a surface of core particle, a step of oxidizing the surface of the nickel plating layer, and a step of directly forming a noble metal plating layer on a surface of the oxidized nickel plating layer. The surface of the nickel plating layer is favorably oxidized by the contact with heated air. In the Ni2p3 spectrum of nickel measured by XPS, the oxidation is favorably executed so that the ratio of Ni-O bonding having the bond energy of 855.7±1.0 eV is ≥60%. <P>COPYRIGHT: (C)2013,JPO&INPIT |
