The steel sheet has a composition containing, by mass, 0.015 to 0.08% C, 0.10 to 0.60% Mn, ≤0.02% P, ≤0.02% S, 0.02 to 0.10% acid-soluble Al and ≤0.006% N. The sum of solid-solution N and solid-solution C, contained in the steel sheet, is 10 to 20 ppm and also a relation of [(solid-solution C)≥(solid-solution N)×2] is satisfied. Temper rolling is performed at a draft of 1.5 to 3.0% and a tension of 50 to 200 MPa using rolls of ≤470 mm roll diameter.
