PROBLEM TO BE SOLVED: To provide an aluminum plated steel sheet or an aluminum - zinc plated steel sheet suitable for high-temperature forming, which acquires high strength after the high-temperature forming. ;SOLUTION: The aluminum plated steel sheet or the aluminum - zinc plated steel sheet suitable for the high-temperature forming, which acquires the high strength after the high-temperature forming, is characterized by including, by mass%, 0.15-0.55% C, ≤0.5% Si, 1.5-3.0% Mn, ≤0.04% S, ≤0.1% P, 0.01-0.10% Al, preferably an appropriate amount of N, B and Ti, and further one or more of ≤1.0% Ni, ≤0.5% Cu, and ≤0.2% Sn, so as to satisfy (Ni+0.5×Cu+3×Sn)≥0.012. The manufacturing method is also disclosed.;COPYRIGHT: (C)2003,JPO
