PROBLEM TO BE SOLVED: To provide a surface treatment method for aluminum or an aluminum alloy capable of depositing an electroless copper plated film by imparting excellent catalyst property without excessive erosion of an electroless nickel film, and ensuring the high adhesiveness of the electroless copper plated film when a surface of aluminum or an aluminum alloy is treated by depositing an electroless nickel film on aluminum or the aluminum alloy, and depositing the electroless copper plated film on the electroless nickel plated film. SOLUTION: An electroless nickel plated film is deposited on aluminum or an aluminum alloy, and an electroless copper plated film is further deposited, through: a process of depositing an electroless nickel plated film by removing an aluminum oxide film deposited on a surface layer of aluminum or an aluminum alloy; a process of depositing an intermediate plated film of Ag, Au, Pd, Pt, Rh and their alloy by the substitution plating or electroless plating on the surface of the electroless nickel plated film; and a process of depositing an electroless copper plated film on a surface of the intermediate plated film.
