Abstract A tin/indium alloy plating solution not containing any cyanide and serving as a substitute for tin/lead alloy plating is provided. The tin/indium alloy plating solution is a weakly alkaline aqueous solution for tin/indium alloy electroplating, prepared by adding, as metal salts, a tetravalent tin salt of metastannic acid and a trivalent indium salt of an organosulfonic acid, further adding a chelating agent, and adjusting the pH of the aqueous solution to a value of 7 to 11 with a caustic alkali.
