PROBLEM TO BE SOLVED: To provide a hot pressed member which is less in the degradation of surface hardness, and has TS (Tensile Strength) of 980 to 2,130 MPa, to provide a steel sheet for the hot pressed member, and to provide a method for producing the hot pressed member. SOLUTION: The hot pressed member is characterized by having a composition that contains, in mass%, 0.09 to 0.38% of C, 0.05 to 2.0% of Si, 0.5 to 3.0% of Mn,≤0.05% of P,≤0.05% of S, 0.005 to 0.1% of Al,≤0.01% of N, 0.002 to 0.03% of Sb and the balance Fe with unavoidable impurities. The hot pressed member is also characterized by having a tensile strength TS of 980 to 2,130 MPa. COPYRIGHT: (C)2011,JPO&INPIT
