Abstract

The present invention provides a fluorine-containing resin being excellent in mold-processability and providing an electric wire jacket having excellent flame retardance, low smoke releasing property, flexibility and mechanical properties. The fluorine-containing resin is a resin for an electric wire jacket substantially comprising, as a resin component, only a fluorine-containing copolymer having a MFR of 11 to 27 g/10 min and comprising tetrafluoroethylene and a perfluoro ethylenically unsaturated compound represented by the formula: CF₂═CF—R_f¹, wherein R_f¹ represents —CF₃ and/or —OR_f²; R_f² represents a perfluoroalkyl group having 1 to 5 carbon atoms. The present invention also provides an electric wire jacket.
