The present invention relates to a fine heating wire, applied to various products by having a small diameter and being bendable and densely installed, and having high thermal efficiency, which includes a core formed with synthetic fiber material and a coil spirally wound around the outer portion of the core, wherein the core connects one or more pairs of poly aramid fiber units, each formed by braiding dozens to hundreds of fine poly aramid fiber strands, to maintain the diameter within 200-600 denier, and the coil is formed of copper or copper alloy to have a temperature rising up to 60° within five minutes when 3.7-12V power is supplied to maintain a resistance value equal to or greater than 0.5 ©/m. The fine heating wire has a minimized diameter to be installed inside slim fiber, and is bendable and densely installed to be applied to gloves, socks, etc. |
