PROBLEM TO BE SOLVED: To provide a switching device for multiply-polarization compatible with a large variety of polarized waves to be transmitted or received, with low loss, high power, and less component parts. SOLUTION: The multi-polarization switching device is provided with first and second input/output terminals where each one is connected to a signal generating part or a receiving part of high frequency signal; third and fourth input/output terminals connected to a V terminal or to an H terminal of an antenna-feeding part; a 90°hybrid circuit for distributing and synthesizing high-frequency signal; a bipolar/double-throw first switch connected between the first input/output terminal, the third input/output terminal, and the 90°hybrid circuit and switched into a first conduction state or a second conduction state; and a bipolar/double-throw second switch connected between the second input/output terminal, the fourth input/output terminal, and the 90°hybrid circuit and switched into the first conduction state or the second conduction state, in conjunction with the first switch.
