Abstract

[Object] To provide a hot-dip zinc-based plated steel sheet excellent in coating film adhesiveness after hot pressing more conveniently. [Solution] A hot-dip zinc-based plated steel sheet according to the present invention includes: a hot-dip zinc-based plated steel sheet that is a base metal; and a surface treatment layer formed on at least one surface of the hot-dip zinc-based plated steel sheet, in which the surface treatment layer contains one or more oxides selected from zirconia, lanthanum oxide, cerium oxide, and neodymium oxide each having a particle size of more than or equal to 5 nm and less than or equal to 500 nm, in a range of more than or equal to 0.2 g/mand less than or equal to 2 g/mper one surface.
