A delivery system for a living body indwelling member includes an elongated shaft portion, a stent disposed on a distal side of the shaft portion, and that is caused to indwell a living body, and contrast markers disposed on at least one side of a proximal side or a distal side of the stent, and that have a contrasting property. The contrast markers are arranged up to a position where the contrast markers do not overlap the stent in a separating direction away from the stent from a position where the contrast markers overlap the stent at an axial position of the shaft portion, or from a position where the contrast markers coincide with an edge portion of the stent. Bending rigidity of the contrast markers on the separating direction side is smaller than on a side where the contrast markers come close to the stent.
