A method of manufacturing a worked-wire product from a wire (10) including, all coaxially arranged, a core conductor (11), an insulator (12), an outer conductor (13), a metal-evaporated film (14) and a sheath (15) is provided. The method comprises the steps of exposing a portion of the outer conductor (13); holding the exposed portion at two positions by gripping with metallic foils (2a; 2b) and fixtures (3; 4); bending the outer conductor (13) about a bending center (S) until it is circumferentially cut off, the bending being effected while applying ultrasonic vibrations on the outer conductor (13) through the fixture (4); removing the cut off portion of the outer conductor (13) to expose a portion of the insulator (12); and removing the exposed portion of the insulator (12) to expose a portion of the core conductor (11).
