PROBLEM TO BE SOLVED: To provide a cold rolled ferritic stainless steel sheet having high elongation and excellent press formability, and to provide its production method. SOLUTION: The steel sheet has a composition comprising, by mass,≤0.03% C,≤0.05% N,≤1% Mn, 13 to 20% Cr and≤0.01% Al, and has a ferrite single structure where Cr carbonitrides with the average grain size of≥0.6μm are dispersed into ferrite grains by≤20 pieces per piece of ferrite grain. In this way, the cold rolled stainless steel sheet having excellent ductility and excellent press formability can be obtained. COPYRIGHT: (C)2007,JPO&INPIT
