A method for manufacturing a can body by forming a circular laminated steel sheet having a radius of R0 includes producing a form at least one time with a laminated steel sheet coated with a polyester resin, which has a plane orientation coefficient of 0.06 or less such that that the height h, the maximum radius r, and the minimum radius d of the form satisfy d≦̸r, 0.2≦̸d/R≦̸0.5, and 1.5≦̸h/(R−r)≦̸2.5, where R represents the radius of the laminated steel sheet having a weight equivalent to the weight of a final form; heating the resulting form at least one time at a temperature of 150° C. or higher, and lower than or equal to the melting point of the polyester resin; and working the heat-treated form into a form satisfying d≦̸r, 0.1≦̸d/R≦̸0.25, and 1.5≦̸h/(R−r)≦̸4.
