Claim 0:
1. A plated steel sheet for hot stamping comprising a base metal steel sheet and a galvanized layer as a plated layer that is formed on a surface of the base metal steel sheet, wherein
the galvanized layer includes a galvannealed layer, a solidified zinc layer, and an oxide layer containing Al, in this order from the base metal steel sheet,
a proportion of a content of Zn (g/m2) in the solidified zinc layer to a content of Zn (g/m2) in the galvanized layer is 10 to 95%, and
a chemical composition of the oxide layer satisfies Formula (i) shown below,

3.0≤Zn/Al≤6.0  (i)

where Zn and Al are contents of Zn and Al (g/m2) contained in the oxide layer, respectively.
