PROBLEM TO BE SOLVED: To provide a metal coating method using a cationic coating composition having an effect for grasping physical properties excellent in corrosion resistance of a coating film and obtaining the physical properties of the coating film, and a coated article. SOLUTION: In applying a metal to an article to be coated, the cationic coating composition containing a substrate resin and a curing agent is used. The coating film comprising this cationic coating composition is characterized in that its glass transition temperature (Tg) is 60-95°C and the oxygen permeability of the coating film with a thickness of 20μm is 5×10<SP>-13</SP>-5×10<SP>-11</SP>(cc×cm/cm<SP>2</SP>×sec×cmHg).
