PROBLEM TO BE SOLVED: To easily obtain a contact component of which wear resistance is greatly improved. SOLUTION: The composite plating 160 includes graphite particles G exposed from nickel plating N. With graphite particles G rolled along the nickel plating N by sliding against a counter part, a stratified graphite-exposed portion 162 is formed. The lubricity of graphite is hereby sufficiently exhibited. The stratified graphite-exposed portion 162 is maintained for a long time since the graphite-exposed portion 162 adheres to a membrane portion 161 by rolling. Moreover, the composite plating 160 is easily produced merely by conducting plating processes after mixing the graphite particles G in a plating bath. Thus, the wear resistance of a switching part in a trigger piece, yoke, and the like, and the wear resistance of a sliding part in a rotor and the like, is greatly improved at low costs.
