A method of manufacturing an electric wire or cable having an improved rubber or plastic insulation layer which has the maximum wall thickness of beam penetration of 4mm or over and whose properties are improved by irradiation with an electron beam, wherein the wire or cable runs under the scanner of an electron beam accelerator while being rotated about the axis of the wire or cable at such a speed as causes the same portion of the wire or cable to be irradiated with the electron beam at least twice during a period of less than 10 seconds; and the electron beam accelerator directs on the insulation layer of the wire or cable an electron beam which is accelerated to an energy of 1 MeV or over and whose maximum penetration range in the said insulation layer is larger than its thickness.
