PROBLEM TO BE SOLVED: To provide a surface treated aluminum material having a coating layer as the outermost layer, not only with high coating film hardness but also with superior adhesiveness of the coating film and impact resistance, on a surface of an aluminum material consisting of aluminum or an aluminum alloy, thereby showing superior performances in coating film hardness, coating film adhesiveness and impact resistance in addition to corrosion resistance, weather resistance and workability which the aluminum material originally has, and to provide a manufacturing method therefor. SOLUTION: The surface treated aluminum material having an anodic oxide layer formed by anodic oxidation on the surface of the aluminum material, and the coating layer forming the outermost layer, comprises that the anodic oxide layer has a film thickness corresponding to the hardness of a base material of the treated surface aluminum material, an that the coating layer has a pencil hardness of 6 H or more. The manufacturing method is a method as above described for manufacturing the surface treatment aluminum material.
