Abstract: Provided is a covered stent manufacturing method including: disposing an inner cover inside a stent body having a mesh structure formed by knitting wires, the stent body having engagement portions, each of which is formed by hooking two bent portions of the wires with each other; disposing an outer cover outside the stent body; forming a slack portion that expands in a radial direction of the stent body in at least one of the covers, the slack portion creating slack that allows movements of the two bent portions in a longitudinal direction and the radial direction of the stent body in at least one of the covers; and joining the covers with each other in regions on an inner side of the mesh of the mesh structure.
