PURPOSE: A cable is provided to prevent cost increase, degradation of insulation due to side products of a crosslinking process by not using crosslinked polyethylene, and to have excellent physical property. CONSTITUTION: A cable comprises at least one conductor(11), and an insulative layer(13) surrounding the conductor. The insulative layer comprises a mixture of polypropylene and ethylene-propylene copolymer. The maximum crystallization temperature is 110-125 °C when detecting crystallization temperature by using differential scanning calorimetry(DSC). The mixture of the polypropylene and ethylene-propylene copolymer has weight average molecular weight of 200,000-450,000, and has number average molecular weight of 40,000-100,000.
