A high-frequency circuit for use in a multiband wireless apparatus for switching the connection between an antenna and transmission/reception circuits depending on signals for pluralities of communications systems, comprising a single-pole, multi-throw switch circuit comprising FET switch circuits between a common port connected to an antenna-side circuit and pluralities of single ports connected to the transmission/reception circuits, and a first matching circuit connected to the common port; the first matching circuit comprising a first inductance element connected in series to a signal path between the antenna and the common port, and a first capacitance element connected to the first inductance element on the antenna side and grounded; the first inductance element making the impedance of the single-pole, multi-throw switch circuit inductive when the single port is viewed from the antenna side; and the first capacitance element adjusting impedance matching between the antenna-side circuit and the transmission/reception circuits.
