    摘要: The invention provides stainless steel for conductive members which exhibits excellent electrical conductivity (namely, low contact electric resistance), and a method for producing such stainless steel. In an exemplary embodiment of the method, stainless steel is dipped into a solution containing fluoride ions at a rate of dissolution of not less than 0.002 g/(m2·s) to less than 0.50 g/(m2·s), thereby incorporating fluorine into a passive film on the steel surface.
