PROBLEM TO BE SOLVED: To provide a stent which effectively shows the functions of the stent in response to a period after detention, by multistep variation in mechanical characteristics.SOLUTION: A stent 100 comprises: linear struts 110 and 111 which form a cylindrical outer periphery with clearances; and plural link parts 120, 130 and 140 which contain biodegradable material and interconnect the struts in the clearances. The stent comprises at least two link parts different in decomposition period under an identical condition.SELECTED DRAWING: Figure 2 【課題】機械特性が多段階的に変化し、留置後の期間に応じてステントの機能が効果的に発揮されるステントを提供する。【解決手段】ステント１００は、隙間が形成された円筒形状の外周を形作る線状のストラット１１０、１１１と、生分解性材料を含み前記隙間でストラット同士を接続する複数のリンク部１２０、１３０、１４０と、を有するステントであって、同一条件下での分解期間が異なる少なくとも２つのリンク部を有する。【選択図】図２
