A stent (1; 10; 20; 30; 40; 50) for placement in living body, formed substantially in a tubular form, the stent (1; 10; 20; 30; 40; 50) comprising a plurality of wave-shaped struts (3, 4), each wave-shaped strut (3, 4) extends in an axial direction from one end side to the other end side of the stent (1; 10; 20; 30; 40; 50), and said plurality of wave-shaped struts (3, 4) is arranged in a circumferential direction of said stent (1; 10; 20; 30; 40; 50), and a plurality of connection struts interconnecting the respective adjacent wave-shaped struts (3, 4), wherein the adjacent wave-shaped struts (3, 4) are provided with a plurality of close sections and open sections, and the connection struts interconnect the adjacent wave-shaped struts (3, 4) between the close sections thereof and each connection strut has at the center thereof a bent portion extending in the axial direction of the stent (1; 10; 20; 30; 40; 50); wherein said plurality of wave-shaped struts (3, 4) are made of a plurality of first wave-shaped struts having a plurality of upper points (31; 33; 36; 38) and a plurality of lower points (32; 34; 37; 39) and a plurality of second wave-shaped struts having a plurality of upper points (42; 44; 47; 49) and a plurality of lower points (41; 43; 46; 48) and each provided between the respective first wave-shaped struts, the respective adjacent first wave-shaped strut and second wave-shaped strut form said close section by permitting the upper point (31, 42; 33, 44; 36, 47; 38, 49) or lower point (32, 41; 34, 43; 37, 46; 39, 48) of one wave-shaped strut and the lower point (32, 41; 34, 43; 37, 46; 39, 48) or upper point (31, 42; 33, 44; 36, 47; 38, 49) of the adjacent other wave-shaped strut to be set substantially in face-to-face relation with each other, and said connection strut interconnects the upper point (31; 33; 36; 38) or lower point (32; 34; 37; 39) of said first-wave-shaped strut and the lower point (41; 43; 46; 48) or upper point (42; 44; 47; 49) of said second wave-shaped strut, which form said close section, characterized in that the stent is arranged such that closed linear bodies of a deformed hexagon, (i) in which distal end side struts, each of which has a free end of the bent portion extending toward the distal end side of the stent, and proximal end side struts, each of which has two bent portions (32, 42; 34, 44; 37, 47; 39, 49) extending toward the proximal end side of the stent and one bent portion extending toward the distal end side of the stent between the two bent portions (32, 42; 34, 44; 37, 47; 39, 49), are connected at two connection points (31, 32; 41, 42; 33, 34, 43, 44; 36, 37, 46, 47; 38, 39; 48, 49) extending along the circumferential direction of the stent, (ii) have partial common portions and are plurally arranged in a zigzag form along the circumferential direction of the stent; wherein the closed linear bodies arranged along the circumferential direction of the stent are such that the adjacent two closed linear bodies in the respective circumferential directions have a common portion. (i) in which distal end side struts, each of which has a free end of the bent portion extending toward the distal end side of the stent, and proximal end side struts, each of which has two bent portions (32, 42; 34, 44; 37, 47; 39, 49) extending toward the proximal end side of the stent and one bent portion extending toward the distal end side of the stent between the two bent portions (32, 42; 34, 44; 37, 47; 39, 49), are connected at two connection points (31, 32; 41, 42; 33, 34, 43, 44; 36, 37, 46, 47; 38, 39; 48, 49) extending along the circumferential direction of the stent, (ii) have partial common portions and are plurally arranged in a zigzag form along the circumferential direction of the stent; wherein the closed linear bodies arranged along the circumferential direction of the stent are such that the adjacent two closed linear bodies in the respective circumferential directions have a common portion.
