    Abstract: An electric wire for an in-vehicle network cable, including a conductor and a covering that covers a periphery of the conductor. The electric wire has a diameter of 0.5 to 1.5 mm. The covering contains a fluororesin that is a tetrafluoroethylene/hexafluoropropylene/perfluoro(alkyl vinyl ether) copolymer. The fluororesin has a melt flow rate of 20 to 40 g/10 min measured at 372° C. under a 5-kg load, a relative permittivity of 2.2 or lower measured at 25° C. and 6 GHz, a melting point of 250° C. or higher, an MIT folding endurance of 2000 times or more, and a tensile elongation at 150° C. of 300% or higher. Also disclosed is an in-vehicle network cable including the electric wire and an in-vehicle network cable including a twisted pair of electric wires, at least one of which is the above-described electric wire for an in-vehicle network cable.
