To provide a method for producing a high-strength cold-rolled steel sheet which has excellent chemical-processing property and corrosion-resistance after electrostatic-deposition coating even in the case of a comparatively high content of Si.

The cold-rolled steel sheet containing Si of 0.8-2.0 mass%, and Mn of 1.0-3.0 mass%, is first subjected to annealing in atmosphere of N2-H2 in a furnace and at a ratio of PH2O/PH2 of 1.010-3. Successively, a quenching and a tempering, are applied, and thereafter, a pickling is performed with an alternating current electrolysis having 1A/dm2 current density. After passing through such sequential process, the high-strength cold-rolled steel sheet having strength of 590 MPa TS and excellent in the chemical-processing property and the corrosion-resistance after electrostatic-deposition coating, is obtained.
