Abstract
A stent is provided, which joins a plurality of stent components via a strut which, even when repeatedly bent over a long period of time, resists breaking. In particular, a stent is provided having a joining portion which integrally joins a stent main wire and a strut, the stent main wire and the strut being fitted into a restraining pipe in a non-joining portion of the stent main wire and the strut near the end of the joining portion. This construction restrains the relative movement of the stent main wire to the strut 4 is restrained and decreased, thus reducing fatigue.
