Abstract
A transmission line includes a laminated body, a first signal conductor layer in the laminated body and extending in a longitudinal direction, and a first ground conductor layer in the laminated body and provided above the first signal conductor layer to overlap the first signal conductor layer in a vertical direction. A first hollow portion is located above the first signal conductor layer and below or adjacent to the first ground conductor layer. The first hollow portion overlaps the first signal conductor layer and the first ground conductor layer in the vertical direction. An insulator layer in the laminated body is above the first hollow portion. A first upper cavity is provided in the first ground conductor layer. At least a portion of the first upper cavity overlaps the first hollow portion and the first signal conductor layer in the vertical direction.
