A mobile station has a transmission/reception antenna, a reception antenna, external connector terminals, and transmitter and receiver circuits. Only the switch circuit, which includes a plurality of switch elements, is interposed between the antennas and external connector terminals, and the transmitter and receiver circuits. The switch circuit switches among modes of connection between the antennas and external connector terminals, and the transmitter and receiver circuits by switching the plurality of switch elements. A control circuit controls the switch circuit so that a signal passes through only one of the plurality of switch elements, by supplying a control signal to the switch circuit.
