1. A wire that transmits a gigahertz band signal comprising:
- a pair of core wires that are twisted with each other;
a pair of first insulation coating materials that coat each of the core wires;
a second insulation coating material that coats the pair of first insulation coating materials; and
a shield material that coats the second insulation coating material and that shields evanescent waves emitted from the pair of core wires, whereinthe pair of core wires have a twisting pitch, a diameter, and a spacing so that the wire has a characteristic impedance of 100 to 200Ω and
the phases of the TEM (Transverse Electro-Magnetic) wave and the evanescent wave that are emitted from the pair of core wires are matched.

Abstract
A wire (a twisted pair cable) that transmits a gigahertz band signal and that is provided with a pair of core wires that are twisted with each other, a first insulation coating material, a second insulation coating material, and a shield material that shields evanescent waves emitted from the pair of core wires. The pair of core wires have a twisting pitch, a diameter, and a spacing so that the wire has a characteristic impedance of 100 to 200Ω and the phases of the TEM (Transverse Electro-Magnetic) wave and the evanescent wave that are emitted from the pair of core wires are matched.
