Abstract: A circuit board includes a board body, a signal conductor, a power supply conductor, and a first reference conductor. The signal conductor is in the board body and a high frequency signal is transmitted through the signal conductor. The power supply conductor is in the board body and is connected to a power supply potential. The power supply conductor extends along at least a portion of the signal conductor. The first reference conductor is in the board body and is insulated from the signal conductor and the power supply conductor.
