The present invention provides a composition for a wire coating material that is a silane-crosslinkable polyolefin-based composition having excellent flame retardancy, and that can reduce moisture adsorption, and an insulated wire and a wire harness using the same. In a composition for a wire coating material mainly composed of a silane-crosslinked polyolefin, (A) a silane-grafted polyolefin obtained by grafting a silane coupling agent to a polyolefin having a density of 0.860 to 0.920 g / cm 3 ; (B) a non-modified polyolefin having a density of 0.860 to 0.955 g / cm 3 , (C) a polymerizable compound having one or two functional groups selected from a carboxy group and an epoxy group, and the functional group A polyolefin copolymerized with at least one polymerizable monomer copolymerizable with a polymerizable compound having (D), (D) an inorganic flame retardant or an inorganic flame retardant aid, and (E) a crosslinking catalyst.
