Plated steel sheet having excellent degreasing properties and method for manufacturiing same

A method for manufacturing a plated steel sheet, the method comprising:

• immersing a base steel sheet in an Al—Mg—Zn-based plating bath to form an Al—Mg—Zn-based plating layer on a surface of the base steel sheet;
• and
• forming a surface coating layer on a surface of the Al—Mg—Zn-based plating layer,
• wherein in the forming of the surface coating layer,
• a metal coating layer consisting of one or more selected from the group consisting of Fe, Zn, Al, and Si is formed by using a material consisting of one or more selected from the group consisting of Fe, Zn, Al, and Si, by using a method selected from the group consisting of a physical vapor deposition method, an electroplating method, and an electroless plating method, or
• an aqueous coating layer is formed by coating a coating solution comprising an oxide, hydroxide, and water-soluble salt of one or more components selected from the group consisting of P, Zn, Mn, Mo, and B, and a solvent to the Al—Mg—Zn-based plating layer and performing heating and drying.
