An insulated electric wire, wherein a conductor is coatednwith a resin composition comprising the following componentsn(A), (B) and (C) and wherein a modulus of elasticity in flexurenof the resin composition is not more than 2,000 Mpa, has goodninsulating property, water resistance and oil resistance ofnpolyolefin and, still, bending property, anti-scrape property,nresistance against deformation by heating and resistancenagainst whitening by bending thereof are improved and, further,nits productivity is good: (A) 100 parts by weight of a mixturenof a microblend and a modified microblend, wherein the microblendncomprises 1 to 70% by weight of polypropylene and 99 to 30%nby weight of a propylene-ethylene random copolymer, and whereinnthe total eluted components fractionated by antemperature-rising elution fractionation method usingno-dichlorobenzene as a solvent comprises (a) 20 to 80% by weightnof a component eluted at -40°C or higher but lower than +20°C,n(b) 10 to 70% by weight of a component eluted at +20°C or highernbut lower than +100°C and (c) 1 to,40% by weight of a componentneluted at +100°C or higher, wherein the sum of the componentn(a), the component (b) and the component (c) is 100% by weight,nwherein the modifiedmicroblend is prepared by bonding an organicnacid group to the microblend, wherein concentration of thenorganic acid group in the mixture is 0.01 to 1 mmol per 1 g nof the total microblend, and the total microblend contains 10nto 90% by weight of a component eluted at -40°C to +30°C in thentotal eluted components fractionatedby the temperature-risingnelution fractionation method using o-dibromobenzene as ansolvent; (B) not more than 700 parts by weight of polypropylene;nand (C) 5 to 200 parts by weight of an ion cross-linking fillernbased on 100 parts by weight of the total amount of the componentn(A) and the component (B). |
