Claim Text:
1. A transmission line comprising: a triplate line including a pair of outer conductors disposed in parallel with each other at a predetermined interval, and a central conductor disposed in a space between the pair of outer conductors; and a spacer interposed in the space between the pair of outer conductors and the central conductor, the spacer being made of a dielectric material and configured to support the central conductor, wherein the spacer includes: wherein the central conductor includes: wherein a line width of the first high-impedance portion is less than a line width of the supported portion, wherein a line width of the second high-impedance portion is less than the line width of the supported portion, wherein a line width of the first main body is greater than the first high-impedance portion, wherein a line width of the second main body is greater than the second high-impedance portion, wherein the supported portion is supported by being sandwiched between the base of the first spacer member and the second spacer member, and has a through-hole into which the protrusion is inserted, and wherein the dielectric material existing between the pair of outer conductors and the central conductor comprises air except for the spacer.
