PROBLEM TO BE SOLVED: To provide a ferritic stainless steel sheet which can suppress the occurrence of a surface flaw and has superior cleanability.SOLUTION: The ferritic stainless steel sheet includes, by mass%, 0.05% or less C, 0.1-2.0% Si, 0.1-1.5% Mn, 10-32% Cr, 0.03% or less Al, and the balance Fe with unavoidable impurities. The mass ratio of Si/Al is adjusted to 20 or more. Furthermore, non-metallic inclusions dispersed in the steel sheet are adjusted to be, by mass%, 10% or less MgO, 40% or less AlO, 10% or less CrO, and the balance Mn(O, S) and SiO. Micropits having depths of 0.5 μm or more and opening areas of 10 μmor more are dispersed on the surface of the steel sheet in the number of 10.0 pits/0.01 mmor less to occupy 1.0% or less by an area rate of the opening parts. |
