Abstract

A coaxial cable includes an inner conductor, an insulator formed on an outer peripheral side of the inner conductor, an outer conductor layer formed on an outer peripheral side of the insulator, and a sheath formed on an outer peripheral side of the outer conductor layer. The outer conductor layer has a first shield layer made of metal foil, an insulating layer formed on an outer peripheral side of the first shield layer, and a second shield layer made of metal foil formed on an outer peripheral side of the insulating layer. The first shield layer of the outer conductor layer is glued to the insulator.

First claim

What is claimed is:

1 . A coaxial cable comprising:
an inner conductor; an insulator formed on an outer peripheral side of the inner conductor; an outer conductor layer formed on an outer peripheral side of the insulator; and a sheath formed on an outer peripheral side of the outer conductor layer, wherein the outer conductor layer has:
a first shield layer made of metal foil;
an insulating layer formed on an outer peripheral side of the first shield layer; and
a second shield layer made of metal foil formed on an outer peripheral side of the insulating layer, and
the first shield layer of the outer conductor layer is glued to the insulator.

2 . The coaxial cable according to claim 1 , wherein each of the first shield layer and the second shield layer is constructed of copper foil and is 30 μm or less in thickness.

3 . The coaxial cable according to claim 2 , wherein each of the first shield layer and the second shield layer is 8 μm or more in thickness.

4 . The coaxial cable according to claim 2 , wherein the first shield layer and the second shield layer have the same thickness.

5 . The coaxial cable according to claim 2 , wherein the first shield layer is once wound on the insulator, and
the second shield layer is once wound on the insulating layer.
