Abstract
An insulated wire having an electrical wire structure capable of reducing a diameter while a direct-current stability property and a flame-retardant property are highly kept is provided. In the insulated wire including: a conductor; a flame-retardant semiconductive layer arranged on an outer periphery of the conductor; an insulating layer arranged on an outer periphery of the flame-retardant semiconductive layer; and a flame-retardant layer arranged on an outer periphery of the insulating layer, an oxygen index of the flame-retardant semiconductive layer defined by JIS K7201-2 is larger than 40, and a volume resistivity of the flame-retardant semiconductive layer defined by JIS C2151 is equal to or smaller than 5.0×10(Ωcm).
