A stent includes a plurality of wavy annular bodies each formed in an annular shape from a wavy linear member, and a connection part provided between the adjacent wavy annular bodies, interconnecting the adjacent wavy annular bodies coaxially, weaker than the wavy annular bodies and rupturable. The connection part extends in a slanting manner relative to an axial direction in which the wavy annular bodies are aligned, and interconnects that one inflexed part of one wavy annular body which is curved in a shape projected toward the other wavy annular body adjacent to the one wavy annular body and that the other inflexed part of the other wavy annular body which is curved in a shape projected toward the one wavy annular body.
