Provided are a stent delivery system and a method for manufacturing the same, whereby high passage properties can be obtained while accuracy of stent implantation is maintained. A stent delivery system (1) having: a long shaft part (20); a balloon (30) capable of expanding by inflow of a fluid therein, the balloon (30) being provided on the external peripheral face of the distal-end part of the shaft part (20); and a stent (70) formed by a wire material so as to be tube-shaped overall while having gaps therein, and mounted on the external peripheral face of the balloon (30) in a contracted state before the balloon (30) expands, the stent (70) being deformed so as to increase in diameter by the expansion of the balloon (30); the stent delivery system (1) wherein the balloon (30) has protruding parts (34) for protruding outward in the radial direction from the gaps in the stent (70) in the contracted state, a lubricant is arranged on at least a portion of the protruding parts (34), and a region where the lubricant is not arranged is provided in at least a portion of the region of the balloon (30) covered by the stent (70). |
