PROBLEM TO BE SOLVED: To provide a stripe laminated steel sheet for a welded can used for a welded can (such as a beverage can, a food can, an aerosol can, a paint can, an 18L can and a pail can), in which the phenomenon that smudge as the powder of tin oxide produced on the surface is scraped by friction with a winding roll at the time of lamination and is transferred to the steel sheet can be prevented, and to provide its production method. SOLUTION: In the stripe laminated steel sheet for a welded can, a plurality of stripes of a thermoplastic resin film are formed in the longitudinal direction of one side of a surface treated steel sheet. Regarding the surface treated steel sheet, the front and back surfaces are provided with a tinned layer having a tin content of 0.7 to 2.0 g/ m<SP>2</SP>and a free tin content of 0.2 to 0.8 g/m<SP>2</SP>, and a chromate-treated layer having a metal chromium content of 5 to 15 mg/m<SP>2</SP>and a chromium oxide content of 5 to 15 mg/m<SP>2</SP>, and the back surface side of the laminated face in which the thermoplastic resin film is formed is provided with an oil-applied layer having an oil content of 0.1 to 10 mg/m<SP>2</SP>.
