PURPOSE: An anodic oxidation surface processing method of a metal is provided to obtain an oxide film in which a corrosion resistance and a hardness etc. are excellent by an electrolyte including a sulfuric acid and an oxalic acid, and by forming a porous oxide film on a surface of a parent metal by applying a voltage after dipping the parent metal in the electrolyte. CONSTITUTION: An anodic oxidation surface processing method of a metal comprises the following steps: a parent metal is preprocessed; the parent metal is an anode; the parent metal is dipped in an electrolyte; a porous oxide film is formed on a surface of the parent metal by applying a voltage; and the electrolyte comprises a sulfuric acid and an oxalic acid.
