A wire comprising:
- a core wire made of a conductor;
- an insulating film covering an outer periphery of the core wire;
- a catalyst adsorption film covering an outer periphery of the insulating film, the catalyst adsorption film including a catalyst serving as a reaction start point of electroless plating;
- and
- an outer periphery conductor covering an outer periphery of the catalyst adsorption film,
- wherein the catalyst adsorption film includes polypyrrole.

A method of manufacturing a wire, the method comprising:
- preparing a coated conducting wire having a structure in which an outer periphery of a core wire made of a conductor is covered with an insulating film;
- forming a catalyst adsorption film on an outer periphery of the coated conducting wire;
- and
- performing electroless plating with a catalyst absorbed to the catalyst adsorption film used as a reaction start point to form an outer periphery conductor on an outer periphery of the catalyst adsorption film;
- and
- performing an electroplating on the outer periphery conductor.
