To provide a composition for a wire coating material, requiring no electron irradiation crosslinking and a less filler, that can produce a crosslinked coat having a high heat resistance, gel fraction and peel property at high temperature, and provide an insulated wire, and a wiring harness. A wire coating material composition contains (A) silane-grafted polyolefin, (B) undenatured polyolefin, (C) functional-group modified polyolefin modified by functional groups of a carboxylic acid group, an acid anhydride group, an amino group and an epoxy group, (D) a bromine flame retardant having a phthalimide structure or the flame retardant and an antimony trioxide, (E) a crosslinking catalyst batch containing a resin containing a crosslinking catalyst, and (F) a zinc oxide and an imidazole compound or a zinc sulfide, (G) a triazine hindered phenolic antioxidant having a melting point of 150 degrees C. or more, and (H) a triazole derivative or a hydrazide metal deactivator.
