PROBLEM TO BE SOLVED: To provide a method of producing a printed film bonded can body, which contributes to improvement in printing efficiency and reduction in production cost, and is free from an inconvenience when heated. SOLUTION: The method of producing the printed film bonded can body has a substrate treatment step, a printing step, a film bonding step, and an ultraviolet irradiation step. In the substrate treatment step, a substrate layer 11 is formed on a surface other than one surface of a thermoplastic resin film 2, on which a clear coat layer is formed. In the printing step, a print layer 12 in a tentatively cured state is formed on a surface of the substrate layer by ejecting ultraviolet curing ink from an ink-jet printer to stick the ink to the surface of the substrate layer, and an adhesive is applied to the print layer, followed by heating and drying the print layer, thereby forming the printed film. In the film bonding step, the printed film is bonded on a can body section of the heated cylindrical can body 1. In the ultraviolet irradiation step, after bonding of the printed film on the can body section, ultraviolet rays are applied to the printed film to permanently cure the ultraviolet curing ink.
