PROBLEM TO BE SOLVED: To provide a steel sheet for vessel excellent in film adhesion and paint adhesion.SOLUTION: A steel sheet for a vessel includes a plated steel sheet having a plating layer covering at least part of a surface of the steel sheet, and a coating film arranged on the surface of the plating layer side of the plated steel sheet. The coating film contains Ti and Ni, wherein the mass ratio (Ni/Ti) of Ni and Ti is less than 1.0. The coating film has a coating weight of 5.0 mg/mor more and less than 60.0 mg/min terms of Ti per one surface of the plated steel sheet and a coating weight of 0.1-3.0 mg/min terms of Ni per one surface of the plated steel sheet. The coating film further includes an organic film on the surface, wherein the organic film includes a carbonyl group.SELECTED DRAWING: None |
