Disclosed is a stent that avoids the occurrence of strain and stress concentration in the drug coat layer due to expansion deformation in the radial direction of the stent as much as possible and does not cause the drug to fall off. The thickness B of the drug coat layer 4 coated on the outer surface of the stent body 2 is gradually reduced toward the bent portion K, and the strain and stress in the drug coat layer 4 due to the expansion deformation of the stent 1 are reduced. It is characterized by avoiding dropout.ステントの放射方向への拡張変形に伴う薬剤コート層での歪の発生や応力集中を極力回避し、薬剤が脱落するおそれのないステントを提供する。ステント本体２の外側表面にコーティングされる薬剤コート層４の厚さＢを屈曲部Ｋに向って漸減し、ステント１の拡張変形に伴う薬剤コート層４での歪や応力を低減させ、薬剤の脱落を回避することを特徴とする。
