PROBLEM TO BE SOLVED: To provide a surface-treated stainless steel sheet having excellent corrosion resistance which sufficiently adheres to a coating film under a severe high-temperature and high-humid environment in a precoated stainless steel sheet. SOLUTION: The surface-treated stainless steel sheet with a stainless steel sheet being a base material is manufactured by setting the ratio D/D<SB>0</SB>of the average thickness D after the treatment to the average thickness D<SB>0</SB>before the treatment to be 0.10-0.90, and then, (1) the steam concentration is≥2.0g/m<SP>3</SP>, and plasma steam is generated in the atmosphere under the atmospheric pressure, and (2) the plasma steam is brought into contact with the surface of the base material.
