The present invention relates to a high-frequency switch circuit which may include a first switch circuit which is connected between a first node connected to a first signal port and a common node connected to a common port and is operated by a first control signal; a second switch circuit which is connected between a second node connected to a second signal port and the common node and is operated by a second control signal having the opposite phase of the first control signal; a first shunt circuit which is connected between the second node and the ground and is operated by the first control signal; a second shunt circuit which is connected between the first node and the ground and is operated by the second control signal; a first inductance circuit which is connected to the first shunt circuit in parallel and performs first parallel resonance in an off-state of the first shunt circuit; and a second inductance circuit which is connected to the second shunt circuit in parallel and performs second parallel resonance in an off-state of the second shunt circuit.
