Abstract

[Object] To provide a zinc-based plated steel sheet excellent in coating film adhesiveness after hot pressing more conveniently. [Solution] A zinc-based plated steel sheet according to the present invention comprises: a zinc-based plated steel sheet that is a base metal; and a surface treatment layer formed on at least one surface of the zinc-based plated steel sheet, in which the surface treatment layer contains one or more oxides selected from titanium oxide, nickel oxide, and tin(IV) oxide each having a particle size of more than or equal to 2 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.
