Abstract:
A steel sheet having a film containing an organic resin and a wax on at least one surface of the steel sheet, in which the organic resin is at least one of an acryl-based resin, an epoxy-based resin, a urethane-based resin, a phenol-based resin, a vinyl acetate-based resin, and a polyester-based resin, in which the wax is a polyolefin wax having a melting temperature of 120° C. or higher and 140° C. or lower and an average particle size of 3.0 μm or less, in which a proportion of the wax in the film is 10 mass % or more, and in which a coating weight per side W (g/m2) of the film and an arithmetic average roughness Ra (μm) of the steel sheet satisfy relational expression (1) below.
W≥0.12×Ra2+0.2 (1)
