<p>PROBLEM TO BE SOLVED: To provide a structure for further improving various characteristics required for a stent.SOLUTION: A stent comprises: multiple annular bodies that have a wavy-line-shaped pattern, respectively, and are arranged side by side in an axial direction; and multiple coil-shaped elements 15 that are arranged between the adjacent annular bodies and extend windingly around an axis line. All top parts on a side where the wavy-line-shaped patterns of adjacent annular bodies face each other are connected to one another by the coil-shaped elements 15. The top parts of the wavy-line-shaped patterns of the annular bodies respectively have a bump-like part 19 that includes: an extension section 19a which extends in the axial direction and is wider than the respective coil-shaped elements 15; and an approximately-semicircular section 19b which is formed at a tip thereof. The respective coil-shaped elements 15 are connected to the bump-like part 19. The extension section 19a of the bump-like part 19 partially has a slit 21 that is formed in a manner extending in the axial direction from each inner peripheral edge of the top parts of the wavy-line-shaped patterns of the annular bodies.</p> |
