<P>PROBLEM TO BE SOLVED: To provide a small diameter coaxial having good and stable electric properties. <P>SOLUTION: The small diameter coaxial cable 10 comprises a core conductor 12, an insulation coat 14, an outer conductive layer 16, and a protection coat 18. For the core conductor 12, a thin wire of copper, copper alloy or single or twisted wire of these thin wires coated with metals of higher conductivity is used. The insulation coat 14 is made of thermoplastic resin and comprises an inner ring 14a just around the core conductor 12, connection parts 14b radially elongated toward outside from the circumference of the inner ring 14a, and an outer ring 14c joined to the outside end of each connection part 14b. Four connection parts 14b are arranged to have intervals of equivalent angle along the direction toward circumference so that four holes 20 which continues in the longer direction are evenly circled up around the center of the core conductor 12. <P>COPYRIGHT: (C)2003,JPO |
