A printed wiring board, which may be included in an electronic apparatus, includes a pair of signal pads including a first signal pad and a second signal pad formed on a front side thereof and configured to transmit differential signals, a ground pad formed at a position in proximity to the pair of signal pads, and a via configured to connect the ground pad to a ground pattern formed either on a back side or on an inner layer of the printed wiring board directly or via a lead wire led out from the ground pad. The via is located at a substantially equal position spaced away from the first signal pad and the second signal pad.
