PROBLEM TO BE SOLVED: To provide a stent capable of suppressing warpage of a valve body of a check valve during the reverse flow of a fluid, and facilitating the opening of the valve body when the fluid flowing inside the stent from the upstream side passes through the valve body.SOLUTION: A stent 10 comprises: a cylindrical stent body 20 formed by processing a metal cylinder and a metal plate or by weaving a metal wire material and a check valve 40 having a resin valve body 43, which is fixed to the tip part of the stent body 20, opens when a fluid flowing into the stent body 20 from the base end side passes therethrough, and closes when the fluid is about to flow into the stent body 20 from the tip side. A taper part 28 whose diameter is gradually reduced toward the tip is formed at the tip part of the stent body 20. The base end side of the check valve 40 is fixed to the inner side of the taper part 28 of the stent body 20, and the check valve 40 is disposed inside the taper part 28.
