Abstract: Disclosed are a resin composition for a cable material and a cable used for a vehicle and a method of manufacturing the cable thereof. In particularly, by controlling the components such as a polypropylene content, a flame retardant content and the like in a base resin, and containing a high crystalline homo polypropylene (PP) resin and a high crystalline block polypropylene resin in the base resin in a specific ratio, the resin composition provides excellent physical properties such as abrasion resistance and flexibility resistance and has reduced weight effect when a cable is manufactured using the resin composition.
