Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a surface treating method by which the working efficiency is made high, the cost is made low, the equipment is made simple as well, furthermore, environmental problems are eliminated, treatment by coils is made possible, and the coating suitability and adhesion strength of stainless steel can be improved. SOLUTION: This is a surface treating method for stainless steel capable of obtaining the surface of stainless steel excellent in adhesion with a coating film of a sealant in which a stainless steel substrate is subjected to cathode electrolytic treatment in a sulfuric acid soln., is thereafter immersed in the same sulfuric acid soln. without being brought into contact with the air from the soln. and is subsequently subjected to cathode electrolysis in a nitric acid soln., by which a stainless steel and a gasket can be obtd.
