CONSTITUTION: The cylindrical stent which is made of wire and includes a shaft in a longitudinal direction, comprises a plurality of base turns and a plurality of connection turns. The base turn is arranged at the interval being two times the height of the base turn in the longitudinal direction and includes a number of peak portions(1c) and a number of valley portions(1b) connected to a straight line portion(1a). The connection turn is arranged in the right and left inclined direction of the base turn and the interval being two times the distance(d) between the straight line portions in the right and left inclined direction. |
