A switching circuit that includes a first transfer path and a second transfer path that transfer a high frequency signal, a first transistor that electrically cuts off a common node between the first transfer path and the second transfer path and the first transfer path if the high frequency signal is transferred via the second transfer path, a second transistor that electrically cuts off the common node and the second transfer path if the high frequency signal is transferred via the first transfer path, a first control voltage input terminal that inputs a high-level control voltage if the high frequency signal is transferred via one of the first transfer path and the second transfer path, and a first voltage supply path that supplies a voltage according to the high-level control voltage to the common node.
