Multilayer wiring board and electronic device including the same

An electronic device comprising:

• a multilayer wiring board having at least a first signal layer and a plurality of ground layers along a stacking direction, the multilayer wiring board comprising:
• a first differential wiring that is provided in the first signal layer and includes a first wiring and a second wiring;
• a first another signal line provided on the first signal layer;
• a signal via that extends along the stacking direction and is electrically connected to the first another signal line;
• and
• a ground via that extends along the stacking direction and is electrically connected to the plurality of ground layers,
• wherein the first differential wiring includes a first portion, a second portion continuous with the first portion, and a third portion continuous with the second portion, the first wiring being disposed between the ground via and the signal via adjacent to the ground via, the second wiring being disposed on an opposite side of the first wiring across the ground via, and the ground via being sandwiched between the first wiring and the second wiring;
• and
• an electronic component mounted on the multilayer wiring board.
