A method of manufacturing a high-tensile steel sheet according to an aspect of the present invention is in weight%, carbon (C): 0.10 to 0.30%, silicon (Si): 0.1 to 1.0%, manganese (Mn): 1.50 to 2.70%, phosphorus (P) ): more than 0 and less than 0.02%, sulfur (S): more than 0 and less than 0.003%, soluble aluminum (Al): 0.01 to 0.10%, chromium (Cr): 0.1 to 1.0%, niobium (Nb): 0.01 to 0.05%, Titanium (Ti): 0.001 ~ 0.05%, boron (B): 0.0001 ~ 0.004%, nitrogen (N): more than 0 0.0060% or less Reheating the steel slab containing the remaining iron (Fe) and other inevitable impurities; Obtaining a hot-rolled sheet by hot finish rolling the reheated steel slab at AC3 ~ 960°C; And cooling the hot-rolled sheet material to a winding temperature: 420 to 650°C, and then winding it.
