PROBLEM TO BE SOLVED: To provide a halogen-free flame-retardant insulated electric wire that can reduce leakage current at high frequency and high voltage, satisfies the required characteristics of flame retardancy and flexibility, and helps reduce environmental load. A halogen-free flame-retardant insulated electric wire having a conductor, a first insulating layer covering the conductor, and a second insulating layer covering the first insulating layer, the first insulating layer comprising a polyester resin 20 to 50 parts by mass, 20 to 50 parts by mass of a polyphenylene ether resin, and 100 parts by mass of a resin component containing a styrene elastomer: polyolefin resin ratio of 0: 100 to 100: 0 It is composed of a first resin composition containing 5 to 70 parts by mass of a flame retardant and having a dielectric constant of 3.2 or less, and the second insulating layer has a metal hydroxide of 150 to A halogen-free flame-retardant insulated electric wire comprising the second resin composition containing 250 parts by mass.
