A stent to be implanted in an organism includes a plurality of wavy annular members arranged in an axial direction thereof. Each of the wavy annular members has a plurality of one-end side bent portions each having an apex at a one-end side of the stent in the axial direction thereof and a plurality of other-end side bent portions each having an apex at an other-end side of the stent in the axial direction thereof. In the wavy annular members disposed adjacently to each other in the axial direction of the stent the wavy annular members disposed at the one-end side of the stent in the axial direction thereof has a sharing linear portion having a start point at the apex of one of the other-end side bent portions thereof or in the vicinity of the apex and a termination point between the apex of the other-end side bent portion thereof and the apex of one of the one-end side bent portions thereof. The sharing linear portion integrates the adjacent wavy annular members with each other.
