To provide a stent capable of indwelling at proper axial length with respect to the pipe axis direction length of an affected region.SOLUTION: A tubular stent 1 for indwelling in a lumen of a living body comprises a plurality of stent parts 11 and 21 capable of being expanded/contracted in a radial direction almost orthogonal to an axial direction. The plurality of stent parts 11 and 21 indwell in the lumen of the living body in such a manner that mutually opposed axial ends overlap each other. In at least one of the plurality of stent parts 11 and 21, a regulation part 2 for regulating axial displacement relative to the other stent part is provided in an area overlapping the other stent part.SELECTED DRAWING: Figure 1 【課題】病変部位の管軸方向長さに対して適正な軸方向長さで留置できるステントを提供する。【解決手段】生体管腔に留置される筒状のステント１であって、軸方向に略直交する径方向に拡縮可能な複数のステント部１１、２１を備える。複数のステント部１１、２１は、互いの対向する軸方向の端部を重ね合わせて生体管腔に留置される。複数のステント部１１、２１のうち少なくとも一方のステント部は、他方のステント部と重なる領域に他方のステント部に対する軸方向の相対的な変位を規制する規制部２を有する。【選択図】図１
