[Problem] To provide a stent and a stent-graft that easily bond to a sharply-curved lesser curvature side of a blood vessel, and that can solve problems such as movement of the stent-graft after being implanted in the affected area, stent fatigue/damage, and internal leakage (endoleaks). [Solution] A stent has ring-shaped units 4 that expand in the circumference CR direction, and connecting units 5 that connect the ring-shaped units 4 to one another in the length L direction. The ring-shaped units 4 are arranged in the length L direction and are connected to one another via the connecting units 5. The ring-shaped units 4 form a substantially zigzag shape by connecting struts 4ST in the circumference CR direction. A terminal-side ring-shaped member 4DE forms an inclined-cut structure that has, as lengths 4STL of the struts 4ST, a largest length 4STLL, a smallest length 4STLS, and a length 4STLM midway between 4STLL and 4STLS, wherein 4STLL>4STLM>4STLS from one direction of a side S toward said one direction of another side S. |
