Provided are: a high-strength steel sheet having superior chemical conversion treatability and post-electrodeposition corrosion resistance even if the amount of contained Si is large; and a method for producing the high-strength steel sheet. A steel sheet containing, by mass%, 0.01-0.18% C, 0.4-2.0% Si, 1.0-3.0% Mn, 0.001-1.0% Al, 0.005-0.060% P, and S=0.01%, the remainder comprising Fe and unavoidable impurities, is continuously annealed, during which the temperature region inside the annealing furnace of at least 750°C is caused to have a dew point within the ambient atmosphere of no greater than -40°C. |
