The purpose of the present invention is to provide a coil winding. Also, the purpose of the present invention is to provides a manufacturing method of the coil winding. For the purpose, the present invention provides a coil winding having a conductive unit including carbon nanotube and conductive material inside of a groove spirally and continuously formed in the outer surface of a cylinder. Provided is a manufacturing method of a coil winding including: a step for treating surface of the outer surface of the cylinder (step 1); a step for manufacturing polymer mold having the cylinder of the step 1 inside (step 2); a step for treating surface of the inner surface of a mold after separating the mold of the step 2 from the cylinder (step 3); a step for fabricating a spirally continued from one end to the other end of the outer surface of the cylinder in which the mold is separated in the step 3 (step 4); a step for covering the mold separated from the step 3 on the cylinder having the fabricated groove (step 5); a step for injecting solution having carbon nanotube and conductive material into a space formed by the groove of the inner surafce of the mold and the outer surface of the cylinder (step 6); a step for removing the mold (step 7). According to the present invention, a coil winding having high thermal stability and small volume is able to be manufactured. [Reference numerals] (AA) CNT + Conductive polymer solution |
