An anti-migration stent includes a hollow stent body formed by interweaving a superelastic shape memory alloy wire diagonally such that upper and lower wires alternately cross over and under each other, forming multiple diamond-shaped spaces. After placing and holding a rod underneath the wire of the hollow stent body, and heating the stent body, an anti-migration bent part is formed on the wire, protruding vertically to form an outline corresponding to a cross-sectional shape of the rod, which makes stent production easy. The stent is prevented from migrating in a lumen of a human body by the bent part protruding vertically and diagonally from the stent body, and easy to insert into and remove from the lumen, preventing the conventional problem damaging an inner surface of the lumen.
