PROBLEM TO BE SOLVED: To provide a zinc-based electrogalvanized steel sheet having high flat sheet part corrosion resistance and flaw part corrosion resistance.SOLUTION: The content of V in a plating film is controlled to 0.5 to below 8 atm% in a range from the boundary between the plating film and a base steel sheet to a height of a 0.1 μm, and is also controlled to 8 atm% or more in a range from the outermost surface of the plating film to a depth of 0.1 μm. |
