For providing a halogen-free resin composition, a covered wire and a wiring harness which can improve mechanical characteristics, abrasion resistance, flame retardant performance and flexibility even if flame retardant is added, a halogen-free resin composition includes a base resin composition of 100 weight division having 45 to 65% by weight of a polypropylene resin, 15 to 30% by weight of a low-density polyethylene resin, and 15 to 30% by weight of a styrene thermoplastic elastomer, and metal hydrate of 80-120 weight division. The styrene thermoplastic elastomer is an aromatic vinyl-conjugated diene system is block copolymer and peak temperature of dynamic factor (tan delta) thereof measured in a range from -100 to 50° C. by a dynamic viscoelasticity measurement device is made in 0-30° C.
