A circuit board includes a plurality of signal lines for transmitting high-frequency signals, a ground electrode positioned between the plurality of signal lines and spaced apart from each of the plurality of signal lines, and a plurality of via conductors connected to the ground electrode. When the circuit board is seen in plan view, the ground electrode has a protruded and recessed area in at least a section of an outer edge thereof, the protruded and recessed area outwardly protruded and inwardly recessed. The plurality of via conductors is positioned in the protruded and recessed area so as to match with a protruded and recessed shape of the protruded and recessed area.
