description Signal transmission characteristics of a semiconductor device are improved. A plurality of wirings of a wiring substrate on which a semiconductor chip is mounted include a first wiring and a second wiring that constitute a differential pair for use in transmitting a differential signal. Moreover, the first wiring and the second wiring respectively have first portions that extend in parallel with each other with a first clearance and second portions that are formed on the same wiring layer as the first portions, and extend in parallel with each other with a second clearance and third portions that are installed between the first portions and the second portions and designed to detour in such directions as to allow the mutual clearance to become greater than the first clearance and the second clearance.
