The purpose of the present invention is to provide a steel plate for containers that maintains excellent corrosion resistance even when a surface treatment that replaces a chromate treatment has been conducted, and that has excellent film adhesion qualities and appearance. This steel plate for containers has, on at least one surface thereof, a chemical conversion coating comprising at least two coatings selected from a zirconium coating that contains zirconium and has a metal zirconium content of 0.1-9mg/m2, a phosphate coating that contains phosphoric acid and has a phosphorous content of 0.1-8mg/m2, and a phenol resin coating that contains phenol resin and has a mass of deposit of 0.5-8/m2 in terms of carbon, the percentage of the area of the surface of the chemical conversion coating layer having particles of a prescribed size being 0.1-50%. |
