PURPOSE: A high-frequency module is provided to keep high isolation between individual terminals of a duplexer, thereby obtaining superior transmitting features. CONSTITUTION: A duplexer comprises a plurality of individual terminals(DRF1) connected to a common terminal(DANT) through each filter. A matching circuit comprises a signal line connected to an RF terminal of a switch device and a common terminal of a duplexer. The matching circuit includes a matching device made of an inductor connected between a signal line and the ground. A wiring electrode of an individual terminal is made of an electrode pattern. A wiring electrode of a common terminal is made of the electrode pattern and the wiring electrode in the individual terminal.
