<P>PROBLEM TO BE SOLVED: To provide a shielded cable capable of realizing flame retardancy without damaging electric characteristics with a low-cost general material in the market in a low-cost structure even in manufacturing. <P>SOLUTION: The shielded cable 11 has conductive wires wound around a outer periphery of a plurality of insulating cores 12 each with an outer periphery of electric conductor 13 insulated with an electric insulator 14 to make up a shielded conductor, an outer periphery of which is covered with an outer casing 17. Metal tape 16 is spirally wound between the shielded conductor 15 and the outer casing, and the casing 17 is formed of flame-retardant polyolefin. Further, drain wires 18 may be arranged in gaps between the plurality of insulating cores 12 and the shielded conductors 15. When the plurality of insulating cores 12 are to be twisted, a winding pitch of the shielded conductor 15 is to be smaller than a twisting pitch of the insulating core 12. Furthermore, an overlapping width of the winding of the metal tape 16 is to be 1/3 to 3/4 of the tape width. <P>COPYRIGHT: (C)2007,JPO&INPIT |
