PROBLEM TO BE SOLVED: To obtain a laminated steel sheet having an appearance which is low in orange peel surface feel and excellent in sharpness. SOLUTION: In the laminated steel sheet, a printed polyethylene terephthalate film is laminated on a surface of the steel sheet, a printed surface of the printed polyethylene teraphthalate film is on an adhesive layer side, which has surface tension 10dyn/cm or over larger than surface tension of the adhesive layer in compared therewith. For that wherein a thermosetting primer layer is provided between the steel sheet and the adhesive layer, surface tension of the thermosetting primer layer is adjusted to 10dyn/cm or over higher than the surface tension of the adhesive layer. |
