A can body for a two-piece can made of a laminated steel sheet, the laminated steel sheet containing a steel sheet and a copolyethylene terephthalate resin layer containing at least hyone member selected from the group consisting of isophthalic acid and cyclohexane dimethanol as a copolymer component in a proportion of 5 to 20 mol %, and having a crystallization temperature of 120° C. to 140° C. on at least one side of the steel sheet; and satisfying the following relationships: r1≰r, 0.1≰r1/R≰0.25, and 1.5≰h/(R−r)≰4, wherein r1 represents the minimum radius of the can body, r represents the maximum radius of the can body, h represents the height of the can body, and R represents the radius of the laminated steel sheet having a circular shape before shaping whose weight is the same as that of the can body. The can body has a high strain level, and does not suffer from delamination and breakage of the resin layer. |
