PROBLEM TO BE SOLVED: To provide a can container body, the bottom part of which can maintain rigidity in reducing thickness of the bottom part 30 of the can and which is equipped with the bottom part capable of assuring self-standing property on an inner pressure increasing certainly and provide a beverage can product using the can container body. SOLUTION: The can container body with a cylindrical body shape having the bottom part is made of a metal material and includes a cylindrical side wall and the bottom part formed continuously to the side wall in one piece, wherein the bottom part is equipped with a dome part curved downward and outward and projected and a curvature supporting leg formed by projecting two or more peripheral edge parts of the dome part which is divided in equal angles, further downward and outward in a curvature shape and when a curvature radius defining curvature of the dome part in the bottom part is made into R<SB>3</SB>(mm), the bottom part satisfies conditions 1.04≤R<SB>3</SB>/D≤1.67 in the relation with diameter D (mm) of the cylindrical side wall.
