PROBLEM TO BE SOLVED: To provide a surface-treated steel sheet superior in, particularly, can-manufacturing workabilities such as drawing ironing workability, seam weldability, film adhesiveness, corrosion resistance and rust resistance, as a material for a laminate vessel. SOLUTION: The rust resistant steel sheet for the laminate vessel has a surface treatment layer containing one or more of Sn, Ni, Fe, Cr and hydrated Cr oxide on at least one surface of a steel sheet, and has an aluminum phosphate compound layer of 0.01 to 500 mg/m<SP>2</SP>in terms of P thereon; or alternatively has the surface treatment layer containing one or more of Sn, Ni, Fe, Cr and hydrated Cr oxide on at least one surface of the steel sheet, and has an organic coating layer of 0.1 to 100 mg/m<SP>2</SP>in terms of C thereon, which contains an phosphoric acid aluminum compound of 0.001 to 50 mg/m<SP>2</SP>in terms of P. Thus manufactured surface-treated steel sheet provides the steel sheet for the laminate vessel, which has superior formability, weldability, film adhesiveness, corrosion resistance and rust resistance.
