Abstract:
Provided is a coated metal sheet for automobile comprising: a metal sheet; and a coating film (α) present on at least one surface of the metal sheet. The coating film (α) contains an organic resin (A), an electrically conductive pigments (B), and anti-corrosion pigments (C), and a Martens micro-hardness HM at −20° C. of the surface of the coating film (α) is 10 to 200 (mg/mm2) at 20 points or more when measured at 100 points, and a Martens micro-hardness HM at 40° C. of the surface of the coating film (α) is 200 to 200,000 (mg/mm2) at 5 points or more when measured at 100 points.
