PROBLEM TO BE SOLVED: To provide a plating method for a base material made from an aluminum alloy, which does not use nitric acid and fluoric acid for a pretreatment liquid for plating, thereby reduces an environmental load, improves a working environment, reduces a chemical cost, reduces a waste liquid treatment cost and imparts adequate adhesiveness to a plated film. SOLUTION: When plating the material made from the aluminum alloy, this plating method includes the pretreatment step of cathodically electrolyzing the aluminum alloy in an acidic solution, which has been treated in an alkali etching step, in order to remove insoluble components in the alloy formed in the etching step.
