Abstract

A tube includes a corrugated metal tubular member; and a first covering part that covers the outside of the tubular member, and forms a braided structure using a resin string member of which at least a part is covered by a metal having lower electrical resistance than that of a metal forming the tubular member. The tube can also include a third covering part made of an insulating resin arranged between the tubular member and the first covering part, and covers the tubular member, wherein the first covering part covers the third covering part.

Claims (15)

1. A tube comprising:

a corrugated metal tubular member; and

a first covering part that covers an outside of the tubular member, and forms a braided structure using a resin string member of which at least a part is covered by a metal having a lower electrical resistance than an electrical resistance of a metal forming the tubular member,

wherein the braided structure includes a first resin string member covered by a metal and a second resin string member not covered by a metal, and the first resin string member and the second resin string member are braided to be alternately arranged.

2. The tube according to claim 1 , further comprising a third covering part made of an insulating resin arranged between the tubular member and the first covering part, and covers the tubular member,

wherein the first covering part covers the third covering part.

3. The tube according to claim 2 , wherein the string member in the first covering part is covered by winding a metal foil having a lower electrical resistance than an electrical resistance of a metal forming the tubular member.

4. The tube according to claim 1 , wherein the string member in the first covering part is covered by winding a metal foil having a lower electrical resistance than an electrical resistance of a metal forming the tubular member.

5. A tube comprising:

a corrugated metal tubular member; and

a second covering part that covers an outside of the tubular member, and forms a braided structure using a metal string member having a lower electrical resistance than an electrical resistance of a metal forming the tubular member in at least a part of the braided structure,

wherein the braided structure includes a resin string member and the metal string member, and the resin string member and the resin metal string member are braided to be arranged alternately.

6. The tube according to claim 5 ,

further comprising a third covering part made of an insulating resin arranged between the tubular member and the second covering part, and covers the tubular member,

wherein the second covering part covers the third covering part.
