PROBLEM TO BE SOLVED: To provide a polygonal can, a method of manufacturing the same, and a can forming apparatus, capable of securing a sufficient withstand load of the polygonal can and capable of preventing a decrease in thickness or unevenness in thickness in a sidewall part.SOLUTION: In a polygonal can W10, a plurality of sidewall parts W2 are connected via corners W3 and both ends are polygonal openings. A sidewall shape part D is formed corresponding to each of the sidewall parts W2. Each sidewall shape part D is formed between corners W3 at both sides of each of the sidewall parts D, and is provided with a bead group B in which at least one group of a plurality of concave beads and a plurality of convex beads extending along a direction from one opening toward the other opening is arranged. |
