Abstract
A transmission line includes a first interlayer connection conductor connecting a first signal conductor and a first mounting electrode, a second interlayer connection conductor connecting a second signal conductor and a second mounting electrode, a third and fourth interlayer connection conductors respectively including third and fourth interlayer connection conductors, and each connecting first and second ground conductors between the first and second signal conductors. The third interlayer connection conductor is closer to the first and second interlayer connection conductors than the fourth interlayer connection conductor is, an adjacent distance between two of the fourth interlayer connection conductors is greater than an adjacent distance between two of the third interlayer connection conductors, and the adjacent distance between the two fourth interlayer connection conductors is less than about ½ of a minimum wavelength of signals transmitted by the first signal conductor and the second signal conductor.
