Abstract: In a printed wiring board, one transmitting circuit and N (N is an integer of 3 or more) receiving circuits are coupled by a multi-point wiring. First to N-th branch points are provided in sequence in the multi-point wiring having one end coupled to the transmitting circuit. Wirings branched at the respective branch points are coupled to the respective receiving circuits. Here, a wiring length from a coupling point of the transmitting circuit to a first branch point is configured to be longer than a wiring length from the first branch point to the second branch point. Wiring lengths between the adjacent branch points at and after a second branch point are configured to be shorter than the wiring length from the first branch point to the second branch point.
