To provide a halogen-free resin composition, an insulated electric wire, and a wire harness, which can maintain long-term thermal resistance without decreasing established mechanical properties, flame retardancy, flexibility, and the like even when the insulated electric wire coated with the halogen-free resin composition is used in a state where it is mixed with an insulated electric wire coated with a PCV resin composition. n The halogen-free resin composition comprises 100 parts by weight of a base resin consisting of 70 to 90% by weight of a polypropylene-based resin and 30 to 10% by weight of an olefin-based or styrene-based thermoplastic elastomer, 50 to 100 parts by weight of a metal hydrate, 3 to 5 parts by weight of a phenol-based antioxidant, 0.1 to 1.0 part by weight of a salicylic acid-based metal scavenger, 3 to 5 parts by weight of a hydrazine-based metal scavenger, and 1 to 10 parts by weight of a metal oxide. |
