Zusammenfassung:	Disclosed herein is a method of testing a corrosion resistance of a coated metal material 1 including an electrodeposition coat 4 on a steel sheet 2. The method includes: treatment of interposing a water-containing material 6 containing water, a supporting electrolyte, and a water penetration enhancer, between a surface of the electrodeposition coat 4 of the coated metal material 1 and an electrode 12; holding of the water-containing material 6 on the surface of electrodeposition coat 4 for one minute to one day; and electrical conduction from the electrode 12 through the water-containing material 6 to the coated metal material 1.
