More particularly, the present invention provides a method for manufacturing long fiber, comprising the steps of: manufacturing conductive long fiber by electrospinning a spinning solution including poly(amide-co-imide) and Poly(trimellitic anhydride chloride-co-4,4′-methylenedianiline), which are mixed in a weight ratio of 4.5:5.5 to 5.5:4.5 (step 1); and coating the surface of the long fiber with conductive particles by immersing the long fiber, which has been manufactured in the step 1, sequentially in aqueous solution of polyethyleneglycol (PEG), solution of conductive metal precursors and washing liquid (step 2), wherein step 2 is conducted continuously as the long fiber is moved to a recovery part for recovering long fiber. The method for manufacturing conductive long fiber according to the present invention does not require many devices or much time compared with existing surface treatment by alkali solution for electroless plating or a method using a precious metal catalyst. In addition, the present invention can be applied easily to industrial scenes as a single process for continuously coating can be developed, thus reducing electroless plating time and increasing productivity greatly.
