Provided is a stent, for example, that enables an improvement in characteristics. A stent 11 includes: a first mesh structure (mesh structure 111) that includes one or more first wire members (wire members W1) and has a tubular structure extending over an entire length in an axial direction Z of the stent 11； and a second mesh structure (mesh structure 112) that is disposed in at least a portion of the stent 11 and includes one or more second wire members (wire members W2) intersecting the first wire members of the first mesh structure. The first wire members are coupled to each other to form a coupling part (coupling parts C11 and C12) in the first mesh structure, and the second wire members are not coupled to each other in the second mesh structure. Moreover, the first wire member has a wire diameter r1 that is smaller than a wire diameter r2 of the second wire member (r1 <； r2).
