A steel sheet for containers comprising: a steel sheet; a Ni coated layer that is formed on at least one surface of the steel sheet; and a chemical treatment layer that is formed on the Ni coated layer, wherein the Ni coated layer contains 10 mg/m 2 to 1,000 mg/m 2 of Ni in terms of an amount of metal Ni, the chemical treatment layer contains 5 mg/m 2 to 30 mg/m 2 of a Zr compound in terms of an amount of metal Zr, an average roughness Ra of an outermost surface of the chemical treatment layer obtained with a scanning probe microscope is 10 nm to 100 nm, and when a variation amount in a yellowness index measured according to condition c of JIS Z-8722 at one measurement point on the outermost surface of the chemical treatment layer is defined as ΔYI represented by Equation, an average of absolute values of the ΔYI obtained at a plurality of the measurement points included in a unit area of the outermost surface is 5.0 or less. Δ ⁢ YI = YI − YI 0 where YI: the yellowness index measured after the steel sheet for containers is subjected to a retort treatment at a temperature of 130°C for 5 hours, YI 0: the yellowness index measured before the retort treatment, wherein YI 0 is measured by cutting out arbitrary 20 portions, which are spaced by at least 10 cm or more, per 1 m 2 from the chemical treatment layer side of the test material into a size of 50 mm × 100 mm to measure the yellowness index YI 0 in an SCI mode, YI is then measured by setting the chemical treatment layer side to be evaluated to a front side and subjecting it to a retort treatment at 130°C for 5 hours, wherein when the temperature in the device reaches 60°C or less, the test material is taken out and dried and then the YI value is measured in an SCI mode, and the absolute value of a ΔYI value, which is a difference between YI and YI 0, is obtained and the total value of these is divided by the number of measurement points to obtain the average of the absolute values of the ΔYI values. a steel sheet; a Ni coated layer that is formed on at least one surface of the steel sheet; and a chemical treatment layer that is formed on the Ni coated layer, wherein the Ni coated layer contains 10 mg/m 2 to 1,000 mg/m 2 of Ni in terms of an amount of metal Ni, the chemical treatment layer contains 5 mg/m 2 to 30 mg/m 2 of a Zr compound in terms of an amount of metal Zr, an average roughness Ra of an outermost surface of the chemical treatment layer obtained with a scanning probe microscope is 10 nm to 100 nm, and when a variation amount in a yellowness index measured according to condition c of JIS Z-8722 at one measurement point on the outermost surface of the chemical treatment layer is defined as ΔYI represented by Equation, an average of absolute values of the ΔYI obtained at a plurality of the measurement points included in a unit area of the outermost surface is 5.0 or less.
