Abstract

A coated steel sheet includes a corrosion-resistant coating composed of at least one layer selected from the group consisting of a Ni layer, a Sn layer, an Fe—Ni alloy layer, an Fe—Sn alloy layer, and an Fe—Ni—Sn alloy layer disposed on at least one surface of a steel sheet, and an adhesive coating disposed on the corrosion-resistant coating, the adhesive coating containing Zr and further containing at least one metal element selected from the group consisting of Co, Fe, Ni, V, Cu, Mn, and Zn, in total, at a ratio by mass of 0.01 to 10 with respect to Zr. The coated steel sheet has excellent humid resin adhesion and corrosion resistance, in which streaky surface defects do not occur.
