Zusammenfassung: | Provided is a plated steel sheet having excellent texture visibility and scratch resistance. A protective film (11) for plating a steel sheet (1) is formed on a plating layer (10) having a texture (T1) on the surface thereof. The protective film (11) contains a binder resin (31) and a plurality of resin particles (32), and the surface of the protective film (11) includes a flat portion (11F) and a plurality of protruding portions (11C) formed so as to partially protrude from the flat portion (11F) by means of the resin particles (32). The average film thickness d of the protective film (11) is 10.0 [mu] m or less, the total area ratio S of the plurality of protrusions in plan view of the surface of the protective film (11) is 10.0% or less, F1 in formula (1) is 10.0 or more, and F2 in formula (2) is 0.7-3.0. F1 = D * S (1) and F2 = D/d (2) (In the formulae, the average particle diameter D ([mu] m) of the resin particles (32) is substituted into 'D', the total area ratio S (%) of the protrusions (11C) is subst |
