Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a rust inhibitor that can form a rust preventive film on a steel surface, which shows a superior anti-rust effect and can be plated with a metal as in the state. SOLUTION: The rust inhibitor for the steel surface comprises an alkaline material such as sodium hydroxide in an amount of 1 to 30 wt.%, a corrosion inhibitor such as quinoline in an amount of 0.05 to 2 wt.%, a phosphate such as ammonium orthophosphate in an amount of 1 to 30 wt.%, an inorganic oxidizing agent such as an alkali metal tungstate in an amount of 0.5 to 10 wt.%, and a nonionic surface-active agent such as a fluorine-based detergent in an amount of 0.0001 to 1 wt.%, and the balance being water.
