There is provided an insulated wire, 10, comprising: a conductor, 11; and an insulated coating layer provided on an outer circumference of the conductor, 12, wherein the insulated coating layer is made of a fluorine-containing elastomer composition containing a base polymer containing tetrafluroethylene-a-olefin copolymer in which tetrafluoroethylene and a-olefin having 2 to 4 carbon atoms are polymerized, and having low smoke emission in which a target value of an optical density at the time of performing a smoke emission test based on a test method 8S5853 is AO (ON) or less represented by the following formula (1), and AO (OFF) or less represented by the following formula (2), when an outer diameter of the insulated wire is defined as d [mm], AO(ON) = ((tan-'(d/45) x 180/7)/451 - {(tan-1(d) x 180/7)/2025) .. (1) AO(OFF) :II 1.5 x AO(ON) .. (2); and low toxicity in which toxic gas total index is 1.0 or less when a toxicity test is performed based on a test method NFX-70-100. The base polymer composition may also include silica. |
