Abstract

A braided wire according to the present invention is constituted by weaving a plurality of first long conductors arranged in parallel and a plurality of second long conductors arranged in parallel so as to cross the first long conductors each other. Each of the first and second long conductors has a section which is perpendicular to an axis thereof and flattened such that a thickness of the conductor is decreased toward both end portions in a width direction. The first and second long conductors each having the flattened section are woven such that they are put one on another in a thickness direction.

Claims

1. A braided wire comprising:

a plurality of first long flat conductors arranged in parallel and a plurality of second long flat conductors arranged in parallel and crossing the plurality of first long flat conductors, the first and second long flat conductors being woven with each other, wherein each of the first and second long flat conductors has a cross section having a first flat side, a second flat side parallel to and longer than the first flat side, and both end sides curved from the first flat side to the second flat side so that both end portions of the cross section in a width direction gradually decrease in thickness and the first flat side of one of the first and second long flat conductors being in contact with the other of the first and second long flat conductors.

2. The braided wire according to claim 1, wherein the section of each of the long conductors crossing the axis thereof is determined such that a ratio (t1/W) of thickness t1 of a middle portion to width W is about (6 to 8)/100, while a ratio (t2/W) of thickness t2 of end portions to width W is about (2 to 3)/100.

3. The braided wire according to claim 1, which is applied to an outer conductor of a coaxial cable constituted of a center conductor, an insulator covering the center conductor, the outer conductor covering the insulator, and an outer coating covering the outer conductor.

4. The braided wire according to claim 1, wherein each of said first and second long flat conductors is a conductor formed by flattening a long conductor having a circular section.
