A stent includes annular units arranged in the axial direction of the stent, wherein each of the annular units includes a plurality of annular elements so arranged as to surround the stent axis, the adjacent annular elements being joined to each other through a joint, and the adjacent annular units are interconnected at their joints by at least one link. The annular elements in each annular unit are so arranged that one of the adjacent pair of annular elements is located on the proximal end side in the axial direction of the stent relative to the other of the adjacent pair of annular elements, end portions of each annular unit are projected zigzag, and the zigzag projected end portion of one annular unit is in the state of penetrating into the adjacent annular unit. The joints in each annular unit are substantially parallel to the stent axis.
