Abstract
A ferritic stainless steel sheet is provided that has a predetermined chemical composition, wherein: a grain size number is 6.0 or more; the ferritic stainless steel sheet satisfies the formulas [A+B≥9.0] and [X+Y≥9.0] with respect to crystal orientation intensities of a ferrite phase obtained by X-ray diffraction; and the sheet thickness is 1.0 mm or more. A represents a {111}<112> crystal orientation intensity at a center portion of sheet thickness, B represents a {111}<112> crystal orientation intensity at a ⅛ portion of the sheet thickness, X represents a {322}<236> crystal orientation intensity at a center portion of sheet thickness, and Y represents a {322}<236> crystal orientation intensity at a ⅛ portion of the sheet thickness.
