In a printed wiring board in which wiring patterns for interconnecting a plurality
of integrated circuits (ICs) operating with synchronizing signals, in order to
make signal transmission times between a plurality of IC's the same, consecutively
formed pairs of an inductance pattern and a capacitive pattern, are constructed
at each of wiring patterns for interconnecting a plurality of IC's. By changing
the shapes of the inductance pattern and the capacitive pattern, it is possible
to adjust signal propagation velocities and signal transmission times.
