A vascular stent (1) for scaffolding a vessel (11) from the inside, wherein the stent is provided with a plurality of tube-forming elements (3A), (3B), and (3C) for forming a tube (2), the tube-forming elements combining with each other to construct a single flow path. Each of the tube-forming elements is formed by bending a strand comprising a single continuous biodegradable polymer, and first and second projecting parts (4, 5) are formed by successive alternation. Formation occurs in multiple stages in the axial direction of the tube by connecting using connecting legs (6) for successively connecting one side of the first projecting part and the other side of the second projecting part where the first and second projecting parts successively alternate. Elastic displacement parts (9) for performing elastic displacement by applying a pressing force to the tube are formed in the middle of the connecting legs successively connecting the first and second projecting parts of the tube-forming elements.
