A transmission line includes a dielectric base body including stacked dielectric layers. A first signal conductor, a second signal conductor, and a ground conductor are included inside the dielectric base body. The first signal conductor includes a first end portion signal conductor and a second end portion signal conductor, which are two end portions in a transmitting direction, and a signal conductor that defines and functions as a main conductor portion. A signal conductor of the second signal conductor and the main conductor portion are provided on different dielectric layers. The signal conductor of the second signal conductor and the signal conductor of the first signal conductor are formed on the same dielectric layer. The ground conductor has an increased width and is located between the signal conductor of the second signal conductor and the main conductor portion in a stacking direction. |
