Abstract
An insulated wire having an electrical wire structure capable of reducing an outer diameter while an insulation property and a flame-retardant property are highly kept is provided. In the insulated wire including: a conductor; and a coating layer arranged on an outer periphery of the conductor, the coating layer includes: a semiconductive layer having a volume resistivity defined by JIS C2151 that is equal to or smaller than 1.0×10(Ωcm); an insulating layer arranged on an outer periphery of the semiconductive layer, the insulating layer having a volume resistivity defined by JIS C2151 that is larger than 5.0×10(Ωcm); and a flame-retardant semiconductive layer arranged on an outer periphery of the insulating layer, the flame-retardant semiconductive layer having a volume resistivity defined by JIS C2151 that is equal to or smaller than 1.5×10(Ωcm) and having an oxygen index defined by JIS K7201-2 that is larger than 40.
