Provided are: hot press-formed (HPF) member with excellent powdering resistance at the time of press forming; and a method for manufacturing the same. The present invention relates to an HPF member with excellent powdering resistance at the time of press forming, the HPF member having a hot-dip coating layer containing Al on a surface of a base steel sheet, wherein the base steel sheet includes, based on wt%, 0.18-0.25% of C, 0.1-1.0% of Si, 0.9-1.5% of Mn, 0.03% or less of P, 0.01% or less of S, 0.01-0.05% of Al, 0.05-0.5% of Cr, 0.01-0.05% of Ti, 0.001-0.005% of B, 0.009% or less of N, the balance Fe, and the other impurities; the hot-dip coating layer comprises a soft diffusion layer and a hard alloy layer; the alloy layer has a Tau phase in the range of 10-30%, in terms of area percent; and the Tau phase contains 10% or more of Si and 0.2% or more of Cr, on the basis of wt% of the Tau phase itself, such that the alloy layer has a thickness of 35 ㎛ or less. |
