Halogen-free flame-retardant cable

A halogen-free flame-retardant cable includes a multi-core twisted wire including a plurality of insulated wires twisted together, the plurality of insulated wires each including a conductor and an insulation layer on an outer periphery of the conductor, an inner layer formed on an outer surface of the multi-core twisted wire, and an outer layer formed on the inner layer. The outer layer includes a resin composition including not less than 30 parts by mass of a flame retardant with respect to 100 parts by mass of thermoplastic polyurethane (TPU). The inner layer includes a resin composition comprising an ethylene-vinyl acetate copolymer (EVA) with a vinyl acetate (VA) content of not less than 33%, and the outer layer is subjected to cross-linking treatment.
