There is provided a stent which can prevent linear configuration elements configuring the stent from being unexpectedly disconnected from each other, while achieving an expansion holding force and excellent flexibility of the stent.A stent (10) has a stent body (20) that is configured to include linear configuration elements, and that has a cylindrical shape having a gap as a whole, a first connection portion (31) and a second connection portion (32) which are integrally formed with the stent body (20) in each of the linear configuration elements adjacent to each other side by side in an axial direction (X) of the stent body (20) having the cylindrical shape, and which are connected to each other while positions overlap in the axial direction (X) and in a circumferential direction (Y) of the stent, and a connection member (40) that includes a biodegradable material for connecting the first connection portion (31) and the second connection portion (32) to each other.
