PROBLEM TO BE SOLVED: To provide a method for consistently manufacturing a high-tensile steel plate containing oxidizable elements with beautiful appearance without any bare spot. SOLUTION: In the method for manufacturing the galvanized high-tensile steel plate, the temperature T of the steel plate dipped in a hot-dip galvanizing bath in a process of executing the hot-dip galvanizing by a continuous hot-dip galvanizing apparatus satisfies the inequalities: T(Zn)+100°C≤T≤T(Zn)+180°C, and 440°C≤T(Zn)≤470°C, where T; the plate temperature T(°C) when the plate is dipped in the hot-dip galvanizing bath, and T(°C); the bath temperature (°C) of the hot-dip galvanizing bath.
