The present invention prevents mispositioning of a stent graft when a plurality of stent grafts are connected and made to indwell. An intravascular indwelling instrument connecting structure (connecting structure of a stent graft set 1), wherein a first intravascular indwelling instrument (first stent graft 10) has, at a connecting section (branch section 12) connecting with a second intravascular indwelling instrument (second stent graft 20), a locking section (13) that protrudes in a radial direction of the connecting section, and the second intravascular indwelling instrument has a lockable section (23) that is positioned on an outer circumferential surface of a film section (21). The lockable section extends in a circumferential direction while bending so as to have bent sections (231a, 231b, 232a, 232b) in an axial direction of the second intravascular indwelling instrument, and the bent sections have first bent sections (231a, 232a) that are on the side farther from the locking section in the axial direction, and second bent sections (231b, 232b) that are on the side closer to the locking section in the axial direction. The first bent sections are fixed to the film section, and the second bent sections can lock to the locking section.
