Abstract: Provided is a hot-stamping shaped article comprising, on the surface of a steel material, a Zn-based plating layer of which an upper layer is a two-phase structure of a G phase and an Fe-Zn solid solution and of which a lower layer excludes the upper layer and is a single-phase structure of the Fe-Zn solid solution, and a Zn oxide layer on the surface of the Zn-based plating layer, wherein the root-mean-square slope R?q of a roughness curve on the surface of the hot-stamping shaped article is at most 0.25, and the area ratio of the Zn oxide layer on the surface of the hot-stamping shaped article is at most 30%. Also provided is a manufacturing method for the same.
