Abstract

A high-frequency transmission line in which the alternating-current resistance is low and that is hard to disconnect is provided. A high-frequency transmission line 2 is a high-frequency transmission line 2 to transmit an alternating-current electric signal, and contains metal and carbon nanotube, and the carbon nanotube is unevenly distributed at a central part 6 of a cross-section that is of the high-frequency transmission line 2 and that is perpendicular to a transmission direction of the alternating-current electric signal.

Claims (3)

1. A high-frequency transmission line to transmit an alternating-current electric signal, the high-frequency transmission line containing metal and carbon nanotube, the carbon nanotube being unevenly distributed at a central part of a cross-section of the high-frequency transmission line, the cross-section being perpendicular to a transmission direction of the alternating-current electric signal, wherein a content rate of the carbon nanotube at the central part is 0.5% to 20% by volume.

2. An antenna comprising the high-frequency transmission line according to claim 1 .

3. An electronic circuit board comprising the high-frequency transmission line according to claim 1 .
