Abstract

The present invention relates to a plated steel sheet for hot press forming, a hot-press forming member manufactured using the same, and a manufacturing method thereof. The plated steel sheet comprises: a base steel sheet and a composite plated layer that is formed on at least one surface of the base steel sheet, and has a Mn-based plated layer and an Al-based plated layer alternately formed therein, an Al-based plated layer being formed on the uppermost layer thereof, wherein the composite plated layer has a total thickness of 5 to 30 μm, and in this case, the Mn-based plated layer accounts for 5 to 60% of the total thickness.
