PURPOSE:To make it possible to carry out a fused cutting, a solder bath soaking, and a hot blast treatment in a good condition, and to improve the terminal processing adaptability, by composing an insulating layer out of a foamy fluorine resin, and specifying a sheath. CONSTITUTION:A coaxial core 10 is composed of a conductor 12, and an insulating layer 14, a shield layer 16, and a sheath 18 formed on the conductor 12 in order, and the conductor 12 is coated with tin, silver, nickel, or the like to improve the soldering process property. In this case, the diameter and the number of the conductor may be selected as desired. On the other hand, the shield layer 16 may be formed either by winding a shield tape lateral or longitudinal over the insulating layer 14, or by winding plural conductors laterally. The insulating layer 14 consists of a foamy fluorine resin, while the sheath 18 consists of a nonbridged polyvinylchloride of the Shore hardness D, 50 to 75. In such a composition, a fused cutting, a solder bath soaking, and a hot blast treatment of the insulating layer and the sheath in the terminal processing of the coaxial core can be carried out in a good condition, and the terminal precessing adaptability can be improved.
