Abstract
There are provided a composite plated product, which has little uneven appearance, a low contact resistance and good wear resistance, and a method for producing the same without the need of any silver-plating solutions containing cyanides and any silver-plating solutions containing silver nitrate as a silver salt. After carbon particles are caused to be suspended in water, an oxidizing agent is added thereto for carrying out a wet oxidation treatment of the carbon particles, and a silver-plating solution, which contains at least one sulfonic acid and the carbon particles treated by the wet oxidation treatment, is used for electroplating a base material to form a coating film of a composite material, which contains the carbon particles in a silver layer, on the base material to produce a composite plated product.
