A ferritic stainless steel sheet excellent in formability, which contains, in mass %, C: 0.001 to 0.010 %, Si: 0.01 to 1.0 %, Mn: 0.01 to 1.0 %, P: 0.01 to 0.04 %, Cr: 10 to 20 %, N: 0.001 to 0.020 %, Nb: 0.3 to 1.0 %, Mo: 0.5 to 2.0 %, and contains precipitates in a total amount of 0.05 to 0.60 mass %; and a method for producing the above ferritic stainless steel sheet, wherein a material for cold rolling is so prepared as to contain Nb based precipitates having a diameter of 0.1 to 1 mum in an amount of 0.15 to 0.6 vol % and/or to contain re-crystallized grains having a diameter of 1 to 40 mum in a recrystallization proportion of 10 to 90 %, and subsequently the material is subjected to cold rolling and then is annealed at 1010 to 1080°C.
