The present invention provides a coated electric wire using a vinyl chloride resin composition suitable for heat-resistant electric wire applications having various properties such as cold resistance and moderate hardness in addition to heat aging resistance and oil resistance. A trimellitic acid ester and a pyromellitic acid ester obtained from a saturated aliphatic alcohol having 4 to 12 carbon atoms and a linear ratio of 50 to 100% based on 100 parts by weight of a vinyl chloride resin. 30 to 60 parts by weight of at least one polycarboxylic acid ester-based plasticizer selected from the group, 3 to 20 parts by weight of a polyester-based plasticizer having a viscosity at 25 ° C of 1000 cps or more, 5 to 40 parts by weight of a hydrotalcite compound And 0.05 to 5 parts by weight of a zinc-based metal soap, the total amount of the plasticizer is 35 to 70 parts by weight, and the ratio of trimellitate in the total plasticizer is 0.5 to 0.5 parts by weight. Hereinafter, a coated electric wire using, as a coating material, a vinyl chloride resin composition in which the ratio of a polyester plasticizer in all plasticizers is 0.4 or less by weight.
