To provide a bioabsorbable stent including: a first tubular unit containing a plurality of cells coupled to each other, each of the cells formed from substantially linear parts and a substantially circular arc part and having a substantially U shape which opens to one end in the axial direction of the stent; and a second tubular unit having the same shape as that of the first tubular unit, the second tubular unit containing a plurality of cells each of which has a substantially U shape which opens to a direction opposite to the opening direction of the opposing first cell. The first tubular unit and the second tubular unit are alternately arranged in sequence to surround a central axis of the stent. Coupling members couple substantially linear parts in some of the opposing cells in the respective neighboring tubular units.
