Seamless can body and method for producing seamless can body

A method for producing a seamless can body, the method comprising:

• a first forming step of forming a metallic blank material into a cup body having a tubular body section, a peripheral bottom section continuing from a lower end of the tubular body section, and a bulging section bulging from the peripheral bottom section toward an opening section by a first height;
• and
• a second forming step of pressing down the bulging section in such a manner that the bulging section has a second height smaller than the first height, to thereby form a peripheral ground section continuing from the lower end of the tubular body section and a raised bottom section continuing from the peripheral ground section toward a center-axis side,
• wherein, when an outer surface area of the raised bottom section is denoted by AD and an area of a plane an outline of which is defined by the peripheral ground section is denoted by AB, a relation of
• 1.55≥(AD/AB)≥1.40
• is satisfied.
