A base member is blasted to roughen the surface. Next, a thermal spray member containing for example Al is formed on the blast treated surface of the base member by a thermal spraying. Next, an extremely thin oxide film at an atom layer level is coated on the surface of the thermal spray member, as an uppermost surface. The oxide film is a layer that is formed from stacked layers of about 15 to 23 atoms, and is formed by an O2 or O3 gas plasma, an atmospheric pressure plasma, or a CVD (chemical vapor deposition) method. A nitride film can be coated instead of the oxide film.
