[PROBLEMS] To provide an electric wire having high discharge start voltage and withstand voltage, excellent heat resistance, excellent wear resistance, and high mechanical strength sufficient to withstand stress caused by a jig during winding. To do. The present invention relates to a conductor, a first insulating layer formed on the outer periphery of the conductor, a fluororesin or polytetrafluoroethylene formed on the outer periphery of the first insulating layer and capable of being melt processed. The first insulating layer is a layer made of a functional group-containing fluororesin that can be melt-processed, and has a 98% cumulative particle diameter of 1 to 10 μm and an average particle diameter. It is an electric wire characterized by being obtained from an aqueous dispersion in which functional group-containing fluororesin particles having a melt processability of 0.3 to 5 μm are dispersed.
