摘要：
The purpose of the present invention is to provide a method for manufacturing a painted metal plate which is resistant to surface stain due to rain streaks. The painted metal plate manufacturing method comprises: a step of forming a coating film on a surface of a metal plate, the coating film having an arithmetic mean roughness Ra of 0.3 to 3.0 µm as calculated according to JIS B0601:2013, and a surface Si atomic concentration of less than 1.0 atm% as measured by X-ray electron spectroscopy using an AlKα beam as an X-ray source; and a step of subjecting the coating film to flame processing at 30 to 1000 kJ/m 2 .
