Claim:
1. A transmission line comprising: a plate-shaped or substantially plate-shaped dielectric body that has a predetermined thickness; a signal conductor that is disposed within the dielectric body and extends in a transmission direction; a reference ground conductor disposed on a side of one of two end surfaces of the dielectric body in a thickness direction; an auxiliary ground conductor disposed on a side of the other end surface of the dielectric body in the thickness direction; and a thickness direction connection conductor that penetrates the dielectric body to connect the reference ground conductor and the auxiliary ground conductor to each other; wherein the auxiliary ground conductor includes a first elongated conductor or substantially elongated conductor and a second elongated conductor or substantially elongated conductor that extend in the transmission direction and are disposed with a predetermined distance therebetween in a direction perpendicular or substantially perpendicular to the transmission direction, and bridge conductors that connect, with predetermined distances therebetween in the transmission direction, the first elongated conductor or substantially elongated conductor and the second elongated conductor or substantially elongated conductor to each other; a plurality of individual transmission portions, which are each based on a set of the reference ground conductor, the auxiliary ground conductor, and the signal conductor, are disposed with respect to the dielectric body, in the direction perpendicular or substantially perpendicular to the transmission direction; and positions of the bridge conductors in the transmission direction in the individual transmission portions adjacent to each other are different.
