PROBLEM TO BE SOLVED: To provide a surface treatment method for aluminum giving excellent corrosion resistance, heat resistance and abrasion resistance in an anodic oxidation treatment and a sealing treatment of the aluminum surface and to provide an aluminum material. SOLUTION: A compound consisting essentially of a hydrate or hydrated oxide of a metal or a compound containing a metal in the above mentioned compound is adsorbed and deposited or allowed to coexist at the pores in an aluminum oxide layer formed on the aluminum surface and at the surface of the oxide layer by applying an anodic oxidation treatment on the aluminum surface in an electrolytic bath using sulfuric acid, oxalic acid, chromic acid, boric acid, etc., as electrolytic solutions or an electrolytic bath containing a hydrate or hydrated oxide of a metal in these electrolytic solutions and further applying a sealing treatment in a solution consisting essentially of a hydrate or hydrated oxide of a metal.
