PROBLEM TO BE SOLVED: To provide an aluminum alloy-made part capable of enhancing the heat conduction performance in the interface between the anodic oxide coating and the base material and the heat radiation performance on the surface of the part concerned, of both of which lowness is problematic in the heat conduction though the part concerned is formed of an aluminum alloy which is excellent in heat conduction, thereby making it possible to make the heat resistance and the adhesion resistance compatible with good heat conductivity and good heat radiation property. SOLUTION: In an aluminum alloy-made part provided with an anodic oxide coating at a prescribed part, silver and/or copper is allowed to contain in the anodic oxide coating. It is desirable to unevenly distribute silver and/or copper by 2 to 30% by mass in the anodic oxide coating in the range of at least 1μm from the interface with the aluminum alloy base material.
