    Abstract: A multilayer wiring board includes: a first differential wiring (30A) wired to a third signal layer (3C); and a second differential wiring (30B) wired to a ninth signal layer (3I). The multilayer wiring board includes a first differential signal via (12A) and a second differential signal via (12B) that are connected to the first differential wiring. The multilayer wiring board includes a third differential signal via (12C) which is connected to the second differential wiring and a stub (41) of which is terminated above the third signal layer. The multilayer wiring board includes a fourth differential signal via (12D) which is connected to the second differential wiring and a stub of which is terminated above the third signal layer, the first differential wiring wired to pass between the fourth differential signal via and the third differential signal via.
