PROBLEM TO BE SOLVED: To provide a stent in which whole length change before/after extension is small and also diameter change before/after extension is large. SOLUTION: The stent 11 is constituted of a net-shaped cylindrical body which is provided with peripheral direction line parts 41 with prescribed length, which extend parallel to each other along a peripheral direction A, and orthogonal line parts 51 connecting the peripheral direction line parts 41 in an acute angle shape. The orthogonal line parts 51 are widened from the acute angle shape to an obtuse angle shape as against the peripheral direction line parts 41 so as to extend in the peripheral direction so that whole length change before/after extension is small and diameter change is made to be large. |
