PROBLEM TO BE SOLVED: To provide a metal can having a stereoscopic effect on a can barrel due to only printing and high designability.SOLUTION: A geometric pattern 2 where polygonal cells are repeatedly formed is added on at least a part of the smooth peripheral wall of a can barrel 1 by printing. The display of a plurality of the cells constituting the geometric pattern 2 is distinguished by three or more gradations of similar colors. A brightest cell having a brightest gradation and a darkest cell having a darkest gradation are adjacent without being separated by a boundary line having a different color from the display colors of the brightest cell and the darkest cell.
