Provided are an electric wire covering material composition, an insulated electric wire, and a wire harness which do not use electron beam crosslinking, reduce filler as a flame retardant as much as possible, have high heat resistance and satisfy flexibility. An insulated wire and a wire harness are configured using a wire coating material composition including the following (A) to (D). (A) Silane grafted polyolefin obtained by grafting a silane coupling agent to polyolefin having a density of 0.860 to 0.900 g / cm3 (B) Unmodified polyolefin having a density of 0.860 to 0.950 g / cm3 (C) Chlorinated polyethylene (D) Silane crosslinking catalyst [selection figure] None |
