PROBLEM TO BE SOLVED: To provide a steel sheet for vessel, which has an excellent resin adhesion and color fastness.SOLUTION: A steel sheet for vessel includes: a steel sheet having a tin plating layer in which the tin plating layer covers at least a part of the surface of the steel sheet; and a coating provided on a surface of the tin plating layer side of the steel sheet having the tin plating layer. The coating includes Zr and Ti. The coating has a coating weight of Zr conversion on one side of the steel sheet having the tin plating layer is 1.0 to 40.0 mg/m, a coating weight of Ti conversion on one side of the steel sheet having the tin plating layer is 0.01 mg/mor more and less than 8.0 mg/m, and a mass ratio of Ti and Zr (Ti/Zr) of the coating is 0.01 or more and less than 0.20, and the coating shows an absorption peak of carbonyl group (C=O) in a range of 1550 to 1800 cmin an infrared absorption (IR) spectrum of the coating. |
