A steel sheet for a hot stamping member contains, as a chemical composition, 0.10 mass% to 0.35 mass% of C; 0.01 mass% to 1.0 mass% of Si; 0.3 mass% to 2.3 mass% of Mn; 0.01 mass% to 0.5 mass% of Al; limited to 0.03 mass% or less ofP; limited to 0.02 mass% or less of S; limited to 0.1 mass% or less ofN; and a balance consisting of Fe and unavoidable impurities, in which a standard deviation of diameters of iron carbides which are contained in a region from a surface to a 1/4 thickness position of the steel sheet is less than or equal to 0.8 µm.
