It is characterized in that when the composite particles containing fine fibers in the particles are produced, a water-soluble metal salt is dissolved in an aqueous solution in which the fine fibers have been dispersed, and that an alkali which reacts with a metal ion dissolved in the aqueous solution to deposit a metal compound is thereafter added to the aqueous solution while maintaining dispersion of the fine fibers, thereby depositing the composite particles containing the fine fibers and comprising the metal compound.

Each of the nickel particles comprises: an outer surface; and a large number of stabber-shaped projections, whose heights are lower than a quarter (¼) of the particle diameter, being integrally formed on the outer surface.

Abstract: The method of producing metallic particles is capable of dispersing fine carbon fibers in an electrolytic solution without using a dispersing agent. The method of producing metallic particles comprises the steps of: electrolyzing an electrolytic solution, in which fine carbon fibers have been dispersed, so as to deposit metallic particles including the fine carbon fibers on a cathode; and separating the deposited metallic particles from the cathode. Vibrations or shocks are applied to the electrolytic solution.
