A zinc-plated steel sheet for hot press molding, which comprises a steel sheet and a zinc plating film formed on the surface of the steel sheet, wherein the steel sheet has a chemical composition containing, in mass%, 0.02 to 0.58% of C, 0.5 to 3.0% of Mn, 0.005 to 1.0% of sol.Al, optional specific components, 2.0% or less of Si, 0.03% or less of P, 0.004% or less of S, 0.01% or less of N, and a remainder made up by Fe and impurities, and wherein the Mn content in a portion of the steel sheet which lays between the interface between the steel sheet and the plating and a region corresponding to the depth of 5 mum in the steel sheet is 0.3 mass% or more, and the zinc plating film is formed in a plating amount of 40 to 110 g/m2, has an Al content of 150 mg/m2 or more and an Al concentration of 0.5 mass% or less. The zinc-plated steel sheet can be heated to 700°C or higher and then subjected to hot press molding. |
