<P>PROBLEM TO BE SOLVED: To provide a coaxial cable capable of improving an insertion property of a sleeve, and preventing reduction of an attenuation amount due to cold impact. <P>SOLUTION: A portion for making an inner insulator 3 coating an inner conductor 2 and a film 4 with a metal foil coating the inner insulator 3 into an approximate close contact state by fusion is formed on a coaxial cable 1 between the inner insulator 3 and the film 4. The portion made into the approximate close contact state by fusion is formed by transmitting heat 10 of a sheath 6 extruded at a temperature higher than a softening point of the inner insulator 3 to the inner insulator 3. Concretely, in the coaxial cable 1, when the heat 10 relating to extrusion molding of the sheath 6 is transmitted to the inner insulator 3, a fusion part 7 is formed between the inner insulator 3 and a resin film part 9 of the film 4 with the metal foil. <P>COPYRIGHT: (C)2013,JPO&INPIT |
