Patent ID: 7548076

Claim:
A coaxial cable, comprising: a signal line; an insulating layer for coating said signal line; a first shield having a tape-like conductor wound around said insulating layer; and a second shield composed of a conductor provided around an outer periphery of said first shield, wherein the first shield further has a tape-like insulator, the tape-like insulator being substantially flat, an entire surface of the tape-like insulator being in contact with part of the tape-like conductor, and the tape-like insulator extending in parallel with the tape-like conductor, wherein said first shield has a tape-like composite taping member composed of a tape-like conductor whose width is wider than said tape-like insulator, said tape-like conductor comprising a first region which contacts said tape-like insulator in parallel and a second region that has a width set in advance from one edge of a tape width direction and that does not overlap with said tape-like insulator, and wherein a value of characteristic impedance between said signal line and said first shield is at most 2.5Ω.
