A stent has a stent body that is configured to include linear configuration elements, a first connection portion and a second connection portion which are integrally formed with the stent body in each of the linear configuration elements adjacent to each other side by side in an axial direction of the stent body having the cylindrical shape, and which are connected to each other while positions overlap in the axial direction and in a circumferential direction of the stent, and a connection member that includes a biodegradable material for connecting the first connection portion and the second connection portion to each other. The stent thus prevents linear configuration elements from being unexpectedly disconnected from each other, while achieving an expansion holding force and excellent flexibility of the stent.
