<P>PROBLEM TO BE SOLVED: To provide a small diameter and lightweight coaxial cable provided with a favorable and stable high frequency characteristic. <P>SOLUTION: The small diameter coaxial cable is provided with a central conductor 12, a cover layer 14, and an outer shield conductor layer 16. The cover layer 14 electrically insulates, and has annular parts 18 and columnar parts 20. The columnar parts 20 radially extend at conformal intervals (90°) in a cross section, and they are extended along the longitudinal direction of the small diameter coaxial cable 10 while maintaining the intervals. The outer shield conductor layer 16 is provided so as to abut on the outer circumference of the columnar parts 20 of the cover layer 14. An interior of the outer shield conductor layer 16 is partitioned by the columnar parts 20. Four continuous voids 22 are formed in the longitudinal direction of the small diameter coaxial cable 10. <P>COPYRIGHT: (C)2004,JPO |
