良好な含ふっ素弾性体被覆電線を得られることになる。It is desirable to use an ethylene-acrylic acid ester copolymer or an ethylene-vinyl acetate copolymer having an acrylic acid ester content and a vinyl acetate content of 5 to 50% by weight, respectively. If it is less than 5% by weight, the compatibility with the other two resins is poor and it is difficult to obtain a good appearance, and if it exceeds 50% by weight, the electrical insulating property of the coating is lowered. Therefore, the tetrafluoroethylene-propylene-based copolymer, the ethylene-tetrafluoroethylene-fluoroolefin copolymer, the ethylene-acrylic acid ester copolymer or the ethylene-vinyl acetate copolymer and the cross-linking aid having the specified values of the present invention are used. A resin composition consisting of a conductor or a conductor shielding layer is extruded and coated to form a coating layer, which is crosslinked by irradiation of ionizing radiation to have a tough coating and a fluorine-containing composition with a good extruded appearance. An elastic body-coated electric wire can be obtained.
