The present invention provides a stent capable of performing inter-organ bypass surgery with minimal invasiveness and a small number of steps for a patient. A cylindrical stent body, a first magnetic body member made of a material containing a magnetic body, loosely fitted on the outer periphery of the stent body so as to be movable in the axial direction of the stent body, and a magnetic material. A second magnetic member 14 made of a material including a body and loosely fitted on the outer periphery of the stent main body 10 so as to be movable in the axial direction of the stent main body 10, and a first magnetic member 12 and a second magnetic member 14, and a regulating member 16 that regulates an axial interval between the first magnetic member 12 and the second magnetic member 14, and includes the first magnetic member 12 and the second magnetic member 12. One or both of the magnetic members 14 have magnets, and the restriction member 16 is made of a material containing a biodegradable material.
