Provided is a coated metal sheet for exterior use, having a metal sheet, and a top coat film situated on the metal sheet. The top coat film contains 0.2-15 volume percent of a gloss control agent composed of porous particles and a delustering agent composed of primary particles. The coated metal sheet satisfies the following expressions in which, in the number-size distribution of the gloss control agent and the delustering agent, R is the number-average particle diameter (μm) of the gloss control agent, D197.5 and D297.5 are 97.5% particle diameter values (μm) of the gloss control agent and the delustering agent, Ru is the upper limit particle diameter (μm) of the gloss control agent, and T is the film thickness (μm) of the top coat film. D197.5/T≦0.7 Ru≦1.2T R≧1.0 2.0≦D297.5/T≦7.0 13≦T≦20.
