Abstract
A power supply line for high-frequency current has a two-layered tubular conductor including an inner tube portion and an outer tube portion which is concentric to the inner tube portion and integrally linked thereto by four connecting portions along the entire length in the longitudinal direction. The four connecting portions are circumferentially disposed at predetermined intervals. By providing the four connection portions between the inner tube portion and the outer tube portion, it is possible to more accurately position the inner tube portion and to reduce high frequency resistance when compared with the likes of conventional power supply lines for high-frequency current having only one connecting portion between an inner tube portion and an outer tube portion.
