PROBLEM TO BE SOLVED: To provide a surface treatment method for an aluminum material where an aluminum nitride (AlN) region having more excellent wear resistance and impact resistance is formed on the surface of an aluminum material. SOLUTION: An aluminum material comprising silicon (Si) and magnesium (Mg) is prepared, the prepared aluminum material is subjected to plasma nitriding treatment, an aluminum nitride (AlN) region is formed on the surface of the aluminum material so as to obtain a structure where a columnar structure and a granular structure are alternately superimposed in the aluminum nitride (AlN) region.
