There is provided a gap coupling type bus system, which makes it possible to mutually transfer data between all the modules connected to the bus. The gap coupling type bus system comprises for at least three modules, each module being provided with at least one sending/receiving circuit for sending and receiving a signal: at least three signal lines (21-26) respectively connected to the at least three modules (11-16); and terminating resistors (31-36) connected to respective signal lines at the other ends of the signal lines, each terminating resistor having generally same value as characteristic impedance of the signal line. Those at least three signal lines (21-26) have portions (1-2, 1-3, 2-3, . . . ) laid in parallel with one another with a predetermined gap, correspondingly to every combination of different two modules out of those at least three modules (11-16).
