PROBLEM TO BE SOLVED: To provide a ferritic stainless steel sheet, superior in surface roughening resistance, along with having superior deep drawability because of having a high r-value. SOLUTION: The steel sheet includes 0.1 mass% or less C, 1.0 mass% or less Si, 1.5 mass% or less Mn, 11-23 mass% Cr, 3 mass% or less Mo, 2 mass% or less Ni, 1 mass% or less Al, 0.06 mass% or less P, 0.03 mass% or less S, 0.04 mass% or less N, and 0.8 mass% or less Nb and/or 1 mass% or less Ti, where these elements satisfy 18<=Nb/(C+N)+2(Ti/(C+N))<=60, includes the balance Fe with unavoidable impurities, and consists of crystal grains which have 75% or more of a ratio of an intergranular length of the grains with an intergranular inclination of 25 degree or higher.
