<p><P>PROBLEM TO BE SOLVED: To provide a surface treated steel sheet manufacturing method in which a surface treated steel sheet that is superior in wet resin adhesion and corrosion resistance and can be an alternative for a tin-free steel sheet is manufactured without using Cr. <P>SOLUTION: The method is characterized in that, after a corrosion resistant film formed of one layer selected from layers of Ni, Sn, Fe-Ni alloy, Fe-Sn alloy, and Fe-Ni-Sn alloy is formed at least on one surface of the steel sheet, an adhesive film is formed by cathodically electrolyzing the steel sheet in an aqueous solution containing ions of Ti, and further containing ions of at least one metal selected from Co, Fe, Ni, V, Cu, Mn, and Zn, wherein Ti is 0.008 to 0.07 mol/l, and the content of at least one metal selected from Co, Fe, Ni, V, Cu, Mn, and Zn relative to Ti is 0.01 to 10 by mole ratio. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
