Provided is a stent capable of preventing protrusion to the outside while preventing shortening even when placed in a curved tubular organ. The stent (10) is equipped with: an inner stent (20) that is formed by fabricating a metal cylinder and is configured by connecting circumferential units, wherein zigzags extending in the circumferential direction are connected into rings or multiple frame-shaped pieces are connected in the circumferential direction, in the axial direction via multiple connecting parts; and an outer stent (30) that is formed into a cylinder by weaving a metal wire material (31) and is fitted on the outer circumference of the inner stent (20). |
