The present invention provides a high-frequency switching circuit comprising: two or more high-frequency switches SW1 and SW2 provided correspondingly to a plurality of communication systems having mutually different frequency bands; and a control circuit DEC1 adapted to control the switching of the two or more high-frequency switches SW1 and SW2, in which a common antenna terminal ANT3 and common terminals ANT1 and ANT2 of the respective high-frequency switches SW1 and SW2 are connected via a matching circuit MAT1 having a filtering function capable of allowing passage of direct current. When one path of the high-frequency switch SW1 is turned on, the other paths of the high-frequency switch SW1 and all paths of the high-frequency switch SW2 can be turned off.
