A seamless can in which an ink layer is transferred onto a can body thereof by a curved surface printing is provided. The ink layer which has been transferred has an overlapping portion which is formed by mutually overlapping a front-end portion of the ink layer and a rear-end portion of the ink layer in a circumferential direction of the can body. An ink area ratio for at least one of the front-end portion and the rear-end portion is smaller than an ink area ratio of an intermediate portion of the ink layer which is adjacent to and continuous with the overlapping portion and excludes the overlapping portion.
