1. A transmission line comprising:
a plurality of layers stacked on each other;
a first signal line on any one of the plurality of layers;
a second signal line on any one of the plurality of layers;
a third signal line on any one of the plurality of layers;
a fourth signal line on any one of the plurality of layers;
a first electrode pad connected to the first signal line;
a second electrode pad connected to the second signal line;
a third electrode pad connected to the third signal line;
a fourth electrode pad connected to the fourth signal line; and
a ground electrode on any one of the plurality of layers; wherein
the plurality of layers are stacked and include a first main surface and a second main surface;
the plurality of layers include:
a line portion extending along the first signal line, the second signal line, the third signal line, and the fourth signal line and including a first end and a second end; and
a first external connection portion connected to the first end of the line portion;
the first electrode pad, the second electrode pad, the third electrode pad, and the fourth electrode pad are on the first main surface in the first external connection portion;
a first frequency of a high-frequency signal to be transmitted through the first signal line and a second frequency of a high-frequency signal to be transmitted through the second signal line are higher than a third frequency of a high-frequency signal to be transmitted through the third signal line and a fourth frequency of a high-frequency signal to be transmitted through the fourth signal line;
each of the first electrode pad and the second electrode pad is surrounded by the ground electrode, in a plan view in a stacking direction of the plurality of layers; and
at least a portion of the third electrode pad and the fourth electrode pad includes a portion that is not surrounded by the ground electrode in the plan view in the stacking direction.
