PROBLEM TO BE SOLVED: To provide an inexpensive cold rolled steel sheet for a gasket material which has excellent gas seal ability while reconciling bead workability with spring properties, to provide its production method, and to provide an inexpensive gasket material which has excellent sealing performance, and is suitably used for opening parts such as an opening for cooling water, an opening for lubricating oil and a bolthole. SOLUTION: The cold rolled steel sheet comprises, by weight, 0.08 to 0.60% C, 1.0 to 3.0% Si, 0.5 to 3.0% Mn,≤0.06% P,≤0.06% S,≤0.1% Al and 0.0010 to 0.0150% N, and the balance Fe with inevitable impurities.
