Abstract (en)

[origin: EP4119252A1] Provided are a seamless can body having excellent pressure resistance and a method for producing the seamless can body. The seamless can body according to the present invention includes a tubular body section (10), a peripheral ground section (20b) continuing from a lower end of the tubular body section, and a raised bottom section (30) continuing from the peripheral ground section toward a center-axis side. When an outer surface area of the raised bottom section is denoted by A<sub>D</sub> and an area of a virtual plane an outline of which is formed by the peripheral ground section is denoted by A<sub>B</sub>, a relation of 1.55 ≥ (A<sub>D</sub>/A<sub>B</sub>) ≥ 1.40 is satisfied.
