Claim:
1. A circuit board comprising: a substrate; a first ground electrode group that includes a plurality of first ground electrodes, each of the plurality of the first ground electrodes being disposed at a corresponding one of vertexes of a first rectangular area in a surface of the substrate; a first pair of signal electrodes disposed in the first rectangular area of the surface, the pair of the signal electrodes being arranged in a first direction parallel to a side of the first rectangular area; a pair of electrode terminals arranged in the first rectangular area of the surface, the pair of the electrode terminals being arranged in a second direction that is perpendicular to the first direction; a pair of first pads arranged in the first rectangular area of the surface, each first pad extending respectively from one of the signal electrodes away from the other signal electrode in the first direction; a pair of second pads arranged in the first rectangular area of the surface, each second pad extending respectively from one of the electrode terminals in the same direction as the first pads; and a pair of capacitors provided above the surface, one end of each capacitor being coupled respectively to one of the first pads and the other end of each capacitor being coupled respectively to one of the second pads.
