PROBLEM TO BE SOLVED: To provide a stent flexible in an axial direction, not contracting in the axial direction at the time of the extension, having large resistance to the contracting force of a blood vessel, capable of uniformly extending a strut and the end parts of which are not curved with a diameter larger than the one of a center part at the time of extension. SOLUTION: This stent is formed in an almost tubular body and is composed of almost wavy constituting elements 2 and 3 expandable in a circumferential direction. A plurality of the almost wavy constituting elements 2 expandable in the circumferential direction are arranged in the almost circumferential direction of the stent without being directly connected to each other, a plurality of the almost wavy constituting elements 3 expandable in the axial direction are arranged in the almost circumferential direction of the stent without being directly connected to each other and they are alternately and cyclically continued in the stent axial direction.
