PURPOSE: A manufacturing method for a removal nail using a spiral reinforcing bar is provided to manufacture and install a removal nail easily and to heighten economical efficiency by low manufacturing cost. CONSTITUTION: The manufacturing method for a removal nail using a spiral reinforcing bar comprises the steps of assembling a spiral reinforcing bar without a rib(12), a space steel wire installed to a part where a rib(12) is removed to secure a rib space, and an end cap, then inputting to a thermal shrinkage tube, and applying heat to reduce the diameter of the thermal shrinkage tube to make the spiral reinforcing bar and the thermal shrinkage tube closely, and pulling out the space steel wire.
