PROBLEM TO BE SOLVED: To provide a small-sized switch module capable of suppressing mutual interferences of signals between mounting electrodes which are used for inputting/outputting each RF signal.SOLUTION: A switch module has a plurality of mounting electrodes for external connection including a common electrode ANT, a plurality of RF signal electrodes TRx1, TRx2, TRx3, TRx4, TRx5, TRx6, TRx7, TRx8, TRx9, TRx10, HiTx, LowTx, control electrodes Vc1, Vc2, Vc3, Vc4, and a power supply electrode VDD which are formed in the peripheral portion of one main face on a wiring board 5. At least one of the power supply electrode VDD and the control electrodes Vc1, Vc2, Vc3, Vc4 is arranged in the respective RF signal electrodes TRx1, TRx2, TRx3, TRx4, TRx5, TRx6, TRx7, TRx8, TRx9, TRx10, HiTx, LowTx. |
