There is provided an insulaled wire, comprising: a conductor; andn an insulated coating layer provided on an outer circumference of the conductor, wherein the insulated coating layer is made of a fluorine-containing elastomer composition containing a base polymer containing tetrafluoroethylene-α-olefin copolymer in which tetrafluoroethylene and α-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 BS6853 is A0 (ON) or less represented by the following formula (1), and A0 (OFF) or less represented by the following formula (2), when an outer diameterof the insulated wire is defined as d [mm], nn A0(ON)={(tan −1 (d/45)×180/π)/45}−{(tan −1 (d)×180/π)/2025} (1)n n A0(OFF)=1.5×A0(ON) (2); andn 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. |
