Abstract: A transmission line substrate includes a stacked body that includes insulating base materials, first and second signal lines, and first and second ground conductors. The second signal line is provided on a layer different from the layer of the first signal line and extends in parallel with the first signal line. The first ground conductor is provided on the same layer as the layer of the second signal line and overlapped with the first signal line when viewed in the Z-axis direction. The second ground conductor is provided on the same layer as the layer of the first signal line and overlapped with the second signal line when viewed in the Z-axis direction. A first transmission line includes the first signal line, the first ground conductor, and an insulating base material, and a second transmission line includes the second signal line, the second ground conductor, and the insulating base material.
