    摘要: 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.

    摘要: The present invention is to provide a printed wiring board which can certainly prevent damage of conductive pattern caused by the terminal. The printed wiring board has a board, a conductive pattern, a through-hole and a non-conductive area. A lead wire of resistance mounted on the printed wiring board is inserted into the through-hole 4. The lead wire projects from a surface of the board, and is bent close to the surface. The non-conductive area is formed into a fan-shaped shape enlarging toward a tip of the lead wire from a center of the through-hole. Since the bent lead wire is arranged on the non-conductive area, the non-conductive area can prevent damage of the conductive pattern which is caused by touching the lead wire to the conductive pattern.
