The present invention relates to a stent that uses a shape memory alloy wire, the stent being an expansion device installed on a part of a body lumen, which is constricted, or which has been constricted, so as to widen the passage of the lumen in response to the lesion part. The purpose of the present invention is to provide a method for manufacturing a stent using a shape memory alloy wire such that the stent maintains a high degree of conformability in a bent portion of a body lumen in which the same is inserted while substantially improving rigidness and durability against continuously applied fatigue, a stent manufactured thereby, and a jig for manufacturing the same. 1. A jig for manufacturing a stent using a shape memory alloy wire , the jig comprising:{'b': '102', 'a body () formed in a vertically long cylindrical shape with a circumference forming a hollow part of a stent to be manufactured; and'}{'b': '103', 'detachable pins () interconnecting the wire by being inserted at multiple split positions around the body in X and Y-axis directions,'}{'b': 1', '3', '5', '7', '9', '11', '13', '102', '2', '4', '6', '8', '10', '12', '14', '1', '1', '14, 'wherein the equator lines (A, A, A, A, A, A, and A) are divided by being spaced by a horizontal diagonal distance (Ph) of a cell forming a rhombic geometry in the X-axis direction from an arbitrary selected origin on the circumferential surface of the body (), and the equator lines (A, A, A, A, A, A, and A) are divided by being spaced by the horizontal diagonal distance (Ph) at locations apart by a length (Ph) bisecting the equator line, thereby forming the equator lines (A to A),'}{'b': 3', '5', '7', '9', '11', '13', '1', '1', '1', '2', '4', '6', '8', '10', '12', '14', '1', '3', '5', '7', '9', '11', '13', '2', '1', '1', '14, 'in a longitudinal direction of the jig, the dividing lines (B, B, B, B, B, and B) are divided by being spaced by a length (Pv) bisecting the dividing line B, which is the reference in the Y-axis ...
