Provided is a surface-treated steel plate: having a corrosion-resistant film comprising at least one layer selected from an Ni layer, Sn layer, Fe-Ni alloy layer, Fe-Sn alloy layer and Fe-Ni-Sn alloy layer, on at least one side of the steel plate; and having an adhesive film containing Zr, and further containing 0.01 to 10 parts in total by mass of at least one type of metal element selected from Co, Fe, Ni, V, Cu, Mn and Zn with respect to Zr, on the corrosion-resistant film. This surface-treated steel plate has excellent wet resin adhesion and corrosion resistance, and striation surface defects do not occur. It is therefore possible to constitute a resin-coated steel plate with outstanding characteristics if the surface-treated steel plate is coated with resin. In addition, with this method of producing a surface-treated steel plate, there is no need to use Cr, which is subject to strict environmental regulation. |
