Abstract

Provided is a hot-stamp formed body comprising a steel base material and a plating layer arranged on a surface of the steel base material, wherein the plating layer has a predetermined chemical composition, and includes, in order from the side of the steel base material, an Fe<2> Al<5> phase and a Fe-Al phase having an Fe content of 20 to 40 mass%, a Zn content of the Fe-Al phase is 1.5 to 15.0 mass%, at a cross-section of the plating layer, an Si content in the Fe<2> Al<5> phase is 5 to 20 mass% and projected lengths L<i> of Fe-Al-Si phases with a circle equivalent diameter of 2 µm or more and a length L<0> of the surface of the steel base material satisfy ΣL<i> /L<0> ≤0.70, and an amount of deposition of the plating layer is 20 g/m<2> or more per side.
