INSULATED WIRE, CABLE AND MOLDED ARTICLE
An insulated wire includes an outermost layer including a resin composition including a fluorine-containing elastomer. A ratio of C═O bond to C—C bond (C═O/C—C) on a surface of the outermost layer is not less than 0.5. The resin composition further includes a tetrafluoroethylene-propylene copolymer and an ethylene-tetrafluoroethylene copolymer as the entire base polymer or a portion of the base polymer at a mass ratio ((of the tetrafluoroethylene-propylene copolymer) to (the ethylene-tetrafluoroethylene copolymer)) in a range of 100:0 to 60:40. The resin composition further includes 5 to 60 parts by mass of calcium carbonate and/or silica as an inorganic filler with respect to 100 parts by mass of the base polymer. The resin composition is cross-linked.
