To provide a covered electric wire using a resin composition which is excellent in flexibility and oil resistance, which is less susceptible to thermal discoloration and which is excellent in moldability. The covered electric wire comprises a core wire and a covering material made of a composition applied around the core wire, wherein the covering material is a melt-moldable resin composition, and, of the resin composition, the volume change after being immersed in an automatic transmission fluid at 165° C. for 70 hours is at most 10%, the flexural modulus is at most 200 MPa, the rate of change in tensile elongation after 2,000 hours of thermal exposure test in air at 200° C. is at most 30%, and the melting point is at least 215° C.
