Abstract
A silver alloy plating bath and a method of forming a silver alloy film by using the silver alloy plating bath and by performing displacement plating on surfaces of a more base metal than silver, the silver alloy plating bath including Ag ions and at least one or more metal ions of Pd ions, Pt ions, Au ions and Rh ions, a concentration of the Ag ions and the metal ion or ions being 0.001 to 0.01 mol/l, a mol ratio of the metal ion or ions to the Ag ions being 1:0.01 to 0.1.
