PURPOSE:To provide a process manufacturing fine wire of titanium wherein the manufacturing process is simpler and the manufacturing time is shorter than the prior art of fine wire of titanium or its alloys (hereinafter called Ti) and in addition, much quantities of necessary degreasing solvent and pickling solution can be reduced. CONSTITUTION:A manufacture of fine wire of Ti characterized by obtaining the fine wire of Ti through removal of copper from this fine copper clad wire after the Ti wire is clad with copper to make copper clad wire then wire drawing and annealing are repeated to make this copper clad wire finer.
