摘要： A coated steel sheet has a coating film on at least one side of a plated steel sheet. The coating film contains a binder resin, non-oxide ceramic particles containing V (excluding VC particles), and doped zinc oxide particles. The respective contents of the non-oxide ceramic particles containing V and the doped zinc oxide particles relative to the coating film satisfy the expressions: [(1) CZn≥10.0, (2) CV≤0.5·CZn, (3) CV≤70−CZn, (4) CV≥0.125·CZn, and (5) CV≥2.0], where CV represents the content (mass %) of the non-oxide ceramic particles containing V, and CZn represents the content (mass %) of the doped zinc oxide particles. The coated steel sheet is excellent in both corrosion resistance before electrodeposition coating, and weldability.
