Abstract: A stent includes a first tubular unit that has a cylindrical tubular shape and a mesh circumferential surface; and a second tubular unit that has a cylindrical tubular shape and a mesh circumferential surface, and is connected to the first tubular unit in a longitudinal axis direction of the stent. The first tubular unit has a first-first direction bent portion which is bent to be convex toward the first direction side that is one side of the longitudinal axis direction, the second tubular unit has a second-second direction bent portion which is bent to be convex toward the second direction side that is the other side of the longitudinal axis direction, and the first-first direction bent portion and the second-second direction bent portion form a first connecting portion that is connected so as to be relatively movable.
