Provided is a stent having a novel structure with which it is possible to suppress distorted deformation at the time of expansion and obtain sufficient strength in the skeleton structure. A stent 10 having a line-shaped body 14 that extends helically in a circumferential direction while reciprocating in an axial direction by continuously alternating straight parts 16 and curved parts 18, wherein the plurality of straight parts 16 in the line-shaped body 14 have a substantially constant thickness throughout the entire stent, and a certain number of the plurality of curved parts 18 in the line-shaped body 14 have different thicknesses.
