PURPOSE: A stent manufacturing method is provided to easily and conveniently manufacture a stent in comparison with an existing netting method and a laser cutting method and to prevent a combining part of each base material from generating a thermal stress. CONSTITUTION: A stent manufacturing method includes a step which prepares two or more base materials of a ring shape; a step which forms an upward protrusion(12) and a downward protrusion(14) in each base material by pressurizing the base material in the diameter direction and the perpendicular direction of the base material; a step which coats the whole or part of the base material with a filler metal; a step which laminates two or more base materials in the protruding direction of the upward protrusion and the downward protrusion; and a step which combines the laminated base material by brazing. The filler metal is coated at the end of the upward protrusion and at the end of the downward protrusion, and two or more base materials are laminated so that the lower protrusion of the upper base material and the upper protrusion of the lower base material meet.
