PROBLEM TO BE SOLVED: To provide an inexpensive and small-sized distributor in which an insertion loss is fixed between respective ports in order to transmit an output signal of a radio transmitting/receiving module to a plurality of other radio transmitting/receiving modules by cable. SOLUTION: The distributor 100 has ports 1 to 6, six signal transmission lines 12 are wired to a wiring board 11 and one end of each signal transmission line 12 is connected to a branching point 13. In addition, an attenuator 14 is provided to each signal transmission line 12. Each attenuator 14 has the same attenuation amount. In addition, one transmission line 15 for connecting the distributor is wired, and an impedance converter 16 and a connector 17 with a switch are provided to the transmission line 15 for connecting the distributor. The inexpensive and small-sized distributor for an evaluation/development system of multi-terminal radio communication is obtained by integrating the attenuator and the distributor. In addition, two distributors 100 can be connected. Thus, the number of ports is increased, namely, the number of radio machines which can be connected at the same time is increased.
