Abstract

A ferritic stainless steel sheet. An first embodiment of the ferritic stainless steel sheet contains 0.1 to 5.0 mass% inclusive of Cu and has a Cu rich layer on the surface thereof wherein the maximum concentration of Cu (Cm) in the Cu rich layer is 10.0 mass% or more and the Fe/Cr ratio at a position at which the maximum concentration of Cu (Cm) is stood at as observed from the surface of the steel sheet in the thickness direction is 2.4 or more. A second embodiment of the ferritic stainless steel sheet contains 0.1 to 5.0 mass% inclusive of Cu and has a Cu rich layer on the surface thereof wherein the maximum concentration of Cu (Cm) in the Cu rich layer is 18.0 mass% or more.
