Summary:PROBLEM TO BE SOLVED: To provide a can body not generating the elution of an exogenous endocrine disrupting chemical substance to content indended for a food can or discoloration such as sulfuration blackening or the like and having good corrosion resistance and beautiful printing appearance. SOLUTION: In a film laminated drawn can (including a deep-drawn can) obtained by one drawing processing or more than one drawing processings due to the press molding processing of a metal panel, an adhesive layer (A) and a thermoplastic polyester resin film layer (B) are provided on the surface of the metal panel becoming the inner surface side of a can. The adhesive layer contains an epoxy/polyester copolymer resin with a number average mol.wt. (Mn) of 6,000-30,000, which is obtained by copolymerizing an epoxy resin and a polyester resin in a weight ratio of 95:5-5:95, and a curing agent, and the drawn can is obtained by performing the molding processing of the metal panel coated with the layers (A) and (B), so that the drawing ratio of the final can body becomes 1.5-2.5 and the strain generated in the thermoplastic resin film layer by molding processing is released.
