Abstract

In a silver-plated product wherein a surface layer of silver is formed on the surface of a base material or on the surface of an underlying layer formed on the base material, the surface layer of silver is formed by electroplating in a silver plating bath which contains 1 to 15 mg/L of selenium and wherein a mass ratio of silver to free cyanogen is in the range of from 0.9 to 1.8, and thereafter, an aging treatment is carried out to produce a silver-plated product wherein an area fraction in {200} orientation of the surface layer is 15% or more.
