The present invention provides a method for producing an aluminum wheel having high corrosion resistance and high adhesion to a coating film, and an aluminum wheel. A surface of an aluminum wheel formed by molding an aluminum base material is subjected to a pickling treatment solution containing 0.5 g / L to 10 g / L of metal ions and 10 g / L to 100 g / L of nitric acid. Use pickling. The pickling treatment liquid contains at least one metal ion selected from the group consisting of Fe 3+ ions, Ni 2+ ions, Co 2+ ions, Mo 6+ ions, and Ce 4+ ions as the metal ions. Use things. Thereby, the cleaning of the surface of the aluminum wheel can be improved, and as a result, when the aluminum wheel is coated, the adhesion to the coating film and the corrosion resistance can be improved.
