PROBLEM TO BE SOLVED: To provide ferritic stainless steel securing both characteristics of ridging characteristics and deep drawability without executing cold rolling and to provided a method for producig the same. SOLUTION: This ferritic stainless steel sheet excellent in ridging characteristics and deep drawability has a composition containing, by mass, 0.0005 to 0.08% C, 0.01 to 1% Si, 0.01 to 2% Mn, <0.04% P, 0.0001 to 0.01% S, 10 to 25% Cr, 0.0005 to 0.08% N and 0.005 to 0.01% Mg, and the balance iron with inevitable impurities, Mg based inclusions with the maximum size of 0.05 to 2μm are present at the density of 20 pieces/mm2 or more in the steel, and the random intensity ratio of the X-ray intensity of the 111} face in the direction vertical to the sheet face is 1 or more. Moreover, as to the method for producing the same, in hot rolling, tandem rolling at a rolling ratio of 80% or more is executed.
