PROBLEM TO BE SOLVED: To provide a ferrite stainless steel sheet for a bellows stock pipe that excels in workability, and is substitutable for an austenite stainless steel. SOLUTION: The ferrite stainless steel sheet for a simplex or duplex bellows stock pipe for an automobile exhaust system having an outer diameter of 28 to 80 mmϕis characterized by containing 10 to 25 mass% of Cr, and having a yield stress of 300 to 450 MPa, an arithmetic average surface roughness of≤0.40μm in terms of Ra and a sheet thickness of≤0.5 mm.
