A stent 2 comprising a ring-shaped stent unit 4 formed by a zigzag-shaped threadlike material 10 continuing in the circumferential direction and expandable in the radius direction R from a contracted state. At least one of turned edge portions 8 a and 8 b of the zigzag-shaped threadlike material 10 composing said stent unit 4 and at least one of turned edge portions 8 a and 8 b of the zigzag-shaped threadlike material 10 in another stent unit 4 being adjacent to the stent unit 4 in the axial direction are connected in the axial direction X by a connection portion 6. The turned edge portions 8 a and 8 b position by being shifted in the axial direction X of the stent from each other between said turned edge portions 8 a and 8 b next to each other in the circumferential direction Y.
