摘要： A hot press-formed article having improved corrosion resistance and coating adhesion when coated is obtained by hot press forming of a zinc-based plated steel material. It has a zinc-based plating layer comprising an iron-zinc solid solution phase and atop it a zinc oxide layer. The average thickness of the zinc oxide layer which is the outermost layer is at most 2 µm. A hot press-formed article having a good appearance and excellent corrosion resistance, coating adhesion, post-coating corrosion resistance, and weldability has a layer (2) consisting essentially of an iron-zinc solid solution phase atop a base material steel sheet (1). It also has a zinc oxide layer (3) with an average thickness of at most 5 µm as an uppermost layer, but it does not have a substantial amount of an iron-zinc intermetallic compound phase. The total amount of Al contained in the iron-zinc solid solution layer (2) and the zinc oxide layer (3) is at most 0.5 g/m 2 , and/or the total amount of Al oxides contained in these layers is at most 5 mg/m 2 .
