The present invention provides a ferritic stainless steel sheet superior in shapeability containing, by wt%, 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%, and Mo: 0.5 to 2.0%, wherein the total precipitates are, by wt%, 0.05 to 0.60%. A method of production of a ferritic stainless steel sheet superior in shapeability comprising producing a cold rolling material in the production process so that the Nb-based precipitates become, by vol%, 0.15% to 0.6% and have a diameter of 0.1 µm to 1 µm and/or so that the recrystallized grain size becomes 1 µm to 40 µm and the recrystallization rate becomes 10 to 90%, then cold rolling and annealing it at 1010 to 1080°C.
