ABSTRACT:
Disclosed is a corrosion resistant conductive part, which is made by forming a thin plated gold layer of thickness 100 nm or less on a stainless steel sheet, and for which high corrosion resistance is guaranteed even with a very thin gold layer. The part is characterized in that the maximum value “v” of atomic concentration of gold given by Auger analysis is at least 98% of the total atomic concentrations of all the elements, which is deemed to be 100%, in the thin gold layer ranging from the surface to the interface of the gold layer and the metal substrate, at which the descending curve of gold crosses the ascending curve of the most predominant component of the substrate metal.
