Provided is a ferritic stainless steel exhibiting excellent corrosion resistance in weld sections. The ferritic stainless steel is characterized by: comprising, in mass%, 0.003-0.014% of C, 0.005-0.016% of N, a total of 0.023% or less of C%+N%, 0.01-0.90% of Si, 0.01-0.50% of Mn, 0.020-0.040% of P, 0.008% or less of S, 0.001-0.090% of Al, 14.5-23.0% of Cr, 0.10-0.60% of Ni, and 0.010-0.040% of V; comprising Ti or Ti and Nb in a range in which the content of Ti is 0.15-0.34 mass%, Ti%+Nb%≤0.70, and V%/(Ti%+0.5×Nb%) is 0.05-0.20, and/or comprising Nb or Nb and Ti in a range in which the content of Nb is 0.35-0.60 mass%, Ti%+Nb%≤0.70, and V%/(Ti%+0.5×Nb%) is 0.05-0.20; and the remainder comprising Fe and unavoidable impurities. |
