A stent has a plurality of wavy annular members arranged adjacently to each other in an axial direction of the stent with the adjacent wavy annular members connected with each other. Each of the wavy annular members has a plurality of one-end side bent portions each having an apex at one-end side of the stent in an axial direction thereof and a plurality of other-end side bent portions each having an apex at the other-end side of the stent in the axial direction thereof. An apex of each of the one-end side bent portions of each wavy annular member penetrates into a space formed between the adjacent other-end side bent portions of one of the adjacent wavy annular members. An apex of each of the other-end side bent portions of each wavy annular member penetrates into a space formed between the adjacent one-end side bent portions of the other of the adjacent wavy annular members. The apex of the one-end side bent portion of each wavy annular member and the apex of the other-end side bent portion of the adjacent wavy annular member curve in an approach direction, thus engaging each other.
