ABSTRACT:
A formed film is formed on the surface of a metal substrate made of an iron-based metal. Thereafter, the surface of the formed film is subjected to treatment for lessening surface roughness such as rolling. In this arrangement, a member which exhibits a sufficient seizing resistance even after being freed of formed film can be obtained.
