PROBLEM TO BE SOLVED: To provide a stent which can suppress a deformation amount in a radial direction with respect to a torsion load.SOLUTION: The stent includes: wavy-line shaped pattern bodies 13 having a wavy-line shaped pattern and arranged in an axial direction LD; and plural coil-shaped elements 15 arranged between the adjacent wavy-line shaped pattern bodies 13 and extended in a spiral shape around an axis. In a view in a radial direction RD perpendicular to the axial direction LD, an annular direction CD of the wavy-line shaped pattern body 13 is inclined with respect to the radial direction RD. In a view in the radial direction RD, an angle θ1 of inclination of a part or the whole of a first virtual straight line L1 connecting virtually apexes 17b connected with the coil-shaped element 15 with respect to the radial direction RD is a first inclination angle equal to or smaller than 30 degrees. A winding direction of one coil-shaped element 15 (15R) positioned on one side in the axial direction LD with respect to the wavy-line shaped pattern body 13 is reverse to a winding direction of the other coil-shaped element 15(15L) positioned on the other side in the axial direction LD.SELECTED DRAWING: Figure 5 |
