PROBLEM TO BE SOLVED: To provide a small high-frequency switching device having superior isolation characteristics using a simple circuital structure. SOLUTION: In the high-frequency switching device, a second port 12c of SPDT(A) 12 as a SPDT switch, having a first port and a second port at one polarity and at an end of two paths separated from the polarity, is grounded via a terminator 12d, while a second port 14c of SPDT(B) 14 is grounded via a terminator 14d. A first port 12b of the SPDT(A) 12 and a first port 14b of the SPDT(B) 14 are individually connected to a first port 16b of the SPDT(C) 16 and to a second port 16c of the SPDT(C) 16.
