Abstract
A coaxial cable includes an internal insulating layer formed on an outer periphery of an electric conductor, and a conductive layer formed on an outer periphery of the internal insulating layer, wherein the conductive layer is made of a metal nanoparticle paste sintered body obtained by sintering metal nanopraticles by irradiation of light toward a metal nanoparticle paste, and an external insulating layer is formed on an outer periphery of the conductive layer.

A manufacturing method of a coaxial cable, comprising the steps of:
- forming a first internal insulating layer, in which a tetrafluoroethylene-perfluoroalkylvinyl ether copolymer is used, on an outer periphery of an electric conductor;
- forming a second internal insulating layer in which a fluorine-containing polymer, with a compound of one kind or more selected from unsaturated carboxylic acid and ester thereof grafted onto a tetrafluoroethylene-perfluoroalkylvinyl ether copolymer is used, on an outer periphery of the first internal insulating layer;
- forming a conductive layer on an outer periphery of the second internal insulating layer, by sintering metal nanoparticles by irradiation of light toward a silver or copper nanoparticle paste which is applied on an outer periphery of the second internal insulating layer;
- and
- forming an external insulating layer, in which the tetrafluoroethylene-perfluoroalkylvinyl ether copolymer is used, on an outer periphery of the conductive layer.
