PROBLEM TO BE SOLVED: To increase the lubrication of the surface by simple surface treatment at a low cost and to reduce the wear at the time of fitting characteristic of the sliding part of a sliding body, on the surface of a ferrous base material, by transfer forming a coating layer of Al or the like softer than that and having a low friction coefficient in such a manner that the metals are rubbed with each other. SOLUTION: On the surface of a ferrous base material such as carbon steel, austenitic stainless steel, martensitic stainless steel or the like, a coating layer softer than the ferrous base material and having a low friction coefficient such as Al, Sb, Pb, Sn, Ag, Cu, Zn, In, their alloys, graphite or the like is transfer formed by friction. This transfer formation can be executed, e.g. while a base material 1 and a transfer material 2 to form into a coating layer are subjected to pressure adhesion, by rotating either, e.g. the base material 1 and rubbing them and forming a coating layer composed of an alloy layer of the base material 1 and the transfer material 2 on the surface of the base material 1 to a thickness of about 0.5 to 5 μm. In this way, the sliding member good in initial fitness, high in heating resistance, enough in wear resistance and capable of contributing to the prolongation of the service life can be obtd.
