<p>A precoated metal sheet which comprises a metal sheet and, formed on a surface thereof, a resin coating film comprising a fluororesin, wherein the concentration proportion of fluorine in an uppermost layer of the resin coating film, as calculated using the equation (1), is 20% or higher and the concentration proportion of fluorine in an inner layer located in a position about 1/2 the thickness of the coating film, as calculated using the following equation (1), is 15% or lower. A(%) = {F/(F+C+O+N×100 (1) (In the equation (1), A is the concentration proportion of fluorine; F is the amount of fluorine in mass%; C is the amount of carbon in mass%; O is the amount of oxygen in mass%; and N is the amount of nitrogen in mass%.)</p> |
