Patent ID: 8268400

Claim:
A method for producing a conductive material, comprising: a depositing step of depositing a conductive fine particle on a surface of a base material; an electrifying step of electrifying the base material in a solution containing a metal ion, using the conductive fine particle as a cathode; and an electroless plating step of subjecting the base material to an electroless plating treatment to deposit a metal on the conductive fine particle, wherein a spherical equivalent diameter of the conductive fine particle, defined as a diameter of a spherical particle having the same volume as the conductive fine particle, is 0.01 to 2 μm, a current density in the electrifying step is 0.01 to 10 A/dm2, an electrifying time in the electrifying step is 0.01 to 60 seconds, and an amount of metal plated in the electrifying step is 1/1000 or less times an amount of metal plated in the electroless plating step.
