CABLE USING FLAT-SHAPED POWDER MAGNETIC MATERIAL AS SHEATHING THEREOF, AND METHOD OF MANUFACTURING SAME

摘要

[Problem] To provide a thin wire-diameter cable that can have the outer circumference thereof sheathed easily with a magnetic material, and wherein flat-shaped magnetic powder is used as the magnetic material for sheathing the outer circumference of the cable. [Solution] A cable (1) has an outer circumference section of a core (10) thereof sheathed with an insulator sheathing section (20) that is formed of an insulator, has a magnetic-material sheathing section (30) comprising flat-shaped powder magnetic powder (30a) formed spirally around the outer circumference section of the insulator sheathing section (20), integrated with the insulator sheathing section, and has the flat-shaped powder magnetic powder (30a) oriented in concentric-circle state with the core (10) as the center thereof. A method of manufacturing the cable is configured so as to be provided with: a first extruder that heats and melts synthetic resin material (40), and forms the insulator sheathing section (20) around the outer circumference of the core (10); and a second extruder that heats and melts magnetic resin material (50), and forms the magnetic-material sheathing section (30) around the outer circumference of the insulator sheathing section (20).
