Abstract:
An insulated electric wire is composed of a conductor, and an insulating layer disposed around an outer circumference of the conductor. The insulating layer is formed from a fluorine-containing elastomer composition, and the fluorine-containing elastomer composition includes a base polymer (A) including 70% by mass or more and 98% by mass or less of a copolymer (a1) of tetrafluoroethylene and an α-olefin having 2 to 4 carbon atoms, and 2% by mass or more and 30% by mass or less of an ethylene-ethyl acrylate copolymer (a2) (excluding an ethylene-ethyl acrylate-maleic anhydride ternary copolymer), and a flame retardant (B) including an antimony compound (b1) and a bromine-based flame retardant (b2), and including 1 part by mass or more and 9 parts by mass or less of the antimony compound (b1), and 0.3 parts by mass or more and 15 parts by mass or less of the bromine-based flame retardant (b2) per 100 parts by mass of the base polymer (A).
