Abstract
Provided is a method of manufacturing a metal nano coil which is suitable for mass production and results in a lower manufacturing cost. The method of manufacturing a metal nano coil includes the steps of: forming, with tension applied to a core member composed of nanofiber of a polymer, a metal thin film on a surface of the core member to fabricate a metal-covered nanofiber; reducing the tension of the metal-covered nanofiber; and heating, with the tension reduced, the metal-covered nanofiber to at or above a boiling point or a thermal decomposition temperature of the polymer and at or below the melting point of the metal thin film to vaporize the core member and shrink the metal thin film into a coil form, so that a hollow metal nano coil is produced.
