The objective of the present invention is to provide a phosphate-treated galvanized steel sheet that exhibits improved workability. The present invention provides a phosphate-treated galvanized steel sheet with improved workability having a phosphate layer deposited on the surface thereof. The steel sheet is characterized in that the phosphate layer contains a polyolefin wax or a modified polyolefin wax. Also provided is a method for producing such a phosphate-treated galvanized steel sheet. The method is characterized in that, following the application of phosphate onto the surface of the galvanized steel sheet, an aqueous solution containing a polyolefin wax or a modified polyolefin wax along with phosphate ions and polyvalent metal ions is applied over the phosphate layer and is then dried. <IMAGE>
